Preparing transducers
WARNINGS
Some transducer sheaths contain natural rubber latex and talc, which can cause
allergic reactions in some individuals. Refer to 21 CFR 801.437, User labeling for
devices that contain natural rubber.
Some gels and disinfectants can cause an allergic reaction on some individuals.
Cautions
To avoid damage to the transducer, use only gels recommended by FUJIFILM
SonoSite. Using gels other than the one recommended by FUJIFILM SonoSite can
damage the transducer and void the warranty. If you have questions about gel
compatibility, contact FUJIFILM SonoSite or your local representative.
FUJIFILM SonoSite recommends that you clean and disinfect transducers after each
use. Refer to Cleaning and disinfecting” on page 91.
Acoustic coupling gel
Acoustic coupling gel must be used during exams. Although most gels provide suitable acoustic coupling,
some gels are incompatible with some transducer materials. FUJIFILM SonoSite recommends Aquasonic
®
gel
and provides a sample with the system.
For general use, apply a liberal amount of gel between the transducer and the body. For invasive procedures,
apply a transducer sheath.
WARNING
To prevent contamination, the use of sterile transducer sheaths and sterile coupling
gel is recommended for clinical applications of an invasive nature. Do not apply the
transducer sheath and gel until you are ready to perform the procedure.
To apply a transducer sheath
To lessen the risk of contamination, install the sheath only when you are ready to perform the procedure.
1 Place gel inside the sheath.
2 Insert the transducer into the sheath.
3 Pull the sheath over the transducer and cable until the sheath is fully extended.
4 Secure the sheath using the bands supplied with the sheath.
Check for and eliminate bubbles between the face of the transducer and the sheath.
Note
Bubbles between the face of the transducer and the sheath may affect the ultrasound
image.
17
5 Inspect the sheath to ensure that there are no holes or tears.
Intended uses
The SonoSite SII ultrasound system is a general purpose ultrasound system intended for use by qualified
physicians and healthcare professionals for evaluation by ultrasound imaging or fluid flow analysis of the
human body.
The system is used with a transducer attached and is powered either by battery or by AC electrical power. The
clinician is positioned beside the patient and places the transducer onto (or into, for invasive procedures) the
patient’s body where needed to obtain the desired ultrasound image.
For the intended transducer for each exam type, refer to “Imaging modes and exams available by
transducer” on page 41.
The system transmits ultrasound energy into the patient’s body to obtain ultrasound images as described
below.
Abdominal Imaging Applications
You can assess the liver, kidneys, pancreas, spleen, gallbladder, bile ducts, transplanted organs, abdominal
vessels, and surrounding anatomical structures for the presence or absence of pathology transabdominally.
Cardiac Imaging Applications
You can assess the heart size and function, cardiac valves, great vessels, visualize blood flow through cardiac
valves, and assess for the presence or absence of pathology. In addition, you can identify the presence and
location of fluid around the heart and lungs used to assist in pericardiocentesis and thoracentesis procedures.
You can detect normal lung motion for the presence or absence of pathology.
Gynecology and Infertility Imaging Applications
You can assess the uterus, ovaries, adnexa, and surrounding anatomical structures for the presence or absence
of pathology transabdominally or transvaginally.
Interventional Imaging Applications
You can use the system to provide ultrasound guidance for biopsy and drainage procedures, vascular line
placement, peripheral nerve blocks, amniocentesis, and other obstetrical procedures and to provide
assistance during abdominal, breast, and neurological surgery.
18 Chapter 2
Obstetrical Imaging Applications
You can assess the fetal anatomy, viability, estimated fetal weight, gestational age, amniotic fluid, and
surrounding anatomical structures for the presence or absence of pathology transabdominally or
transvaginally. CPD and Color imaging are intended for high-risk pregnant women. High-risk pregnancy
indications include, but are not limited to, fetal hydrops, placental abnormalities, as well as maternal
hypertension, diabetes, and lupus.
WARNINGS
To prevent injury or misdiagnosis, do not use this system for Percutaneous
Umbilical Blood Sampling (PUBS) or in vitro Fertilization (IVF) The system has not
been validated to be proven effective for these two uses.
CPD or Color images can be used as an adjunctive method, not as a screening tool,
f
or the detection of structural anomalies of the fetal heart, and as an adjunctive
method, not as a screening tool, for the diagnosis of Intrauterine Growth
Retardation (IUGR)
Pediatric and Neonatal Imaging Applications
You can assess the pediatric and neonatal abdominal, pelvic, and cardiac anatomy, pediatric hips, neonatal
head, and surrounding anatomical structures for the presence or absence of pathology.
Superficial Imaging Applications
You can assess the breast, thyroid, testicle, lymph nodes, hernias, musculoskeletal structures, soft tissue
structures, ophthalmic structures, and surrounding anatomical structures for the presence or absence of
pathology. You can use the system to provide ultrasound guidance for biopsy and drainage procedures,
vascular line placement, and peripheral nerve blocks.
WARNING
To avoid injury to the patient, use only an Ophthalmic (Oph) exam type when
performing imaging through the eye. The FDA has established lower acoustic
energy limits for ophthalmic use. The system will not exceed these limits only if the
Oph exam type is selected.
Vascular Imaging Applications
You can assess the carotid arteries, deep veins, and arteries in the arms and legs, superficial veins in the arms
and legs, great vessels in the abdomen, and various small vessels feeding organs for the presence or absence

box unselected unless you use FUJIFILM SonoSite software products. For more
information, refer to the ultrasound systems DICOM conformance statement.
Limitations of JPEG format
When transferring or exporting images in JPEG format, the system uses lossy compression. Lossy compression
may create images that have less absolute detail than BMP format and that don’t render identically to the
original images.
In some circumstances, lossy-compressed images may be inappropriate for clinical use. For example, if you use
images in SonoCalc
®
IMT software, you should transfer or export them using BMP format. SonoCalc IMT
software uses a sophisticated algorithm to measure images, and lossy-compression may cause errors.
For more information on using lossy-compressed images, consult the industry literature, including the
following references:

Needle visualization
WARNINGS
To avoid incorrect needle placement when Steep Needle Profiling (SNP) is on:
Use only FUJIFILM SonoSite or CIVCO approved needle guides, brackets, supplies,
c
omponents, and accessories. Other brands may not properly fit FUJIFILM
SonoSite transducers.
Use only needle guides compatible with the transducers listed in Table 4-4,
“Transducers and exam types available with SNP” on page 37.
Using movement and fluid injection, verify the needle-tip location and trajectory.
Steep Needle Profiling technology enhances linear structures within a selected
angle range on the ultrasound plane. Linear structures outside the selected angle
range or the ultrasound planesuch as a bent needlemay be less apparent.
Note that linear structures are enhanced only in an outlined portion of the image.
The area outside the outline remains unchanged.
Note that the beam divergence of a curved array transducer may prevent a
segment of the needle shaft from showing in the image. The needle tip may not
show.
About Steep Needle Profiling technology
The SNP control turns on Steep Needle Profiling technology (formerly SonoMBe™ imaging), which enhances
linear structures within a selected angle range and can facilitate needle guidance during catheter placement
and nerve-block procedures. A three- or four-sided outline indicates the enhancement area as shown in
Figure 4-1 on page 38.
For curved array transducers, Steep Needle Profiling technology can help identify the direction of the needle,
although only segments of the needle shaft may show in the image. See Figure 4-2 on page 38. Use
movement and fluid injection to help verify the needle-tip location.
The SNP control is available in 2D full-screen imaging only and on the following:

Figure 4-1 Image with SNP on (linear transducer)
Figure 4-2 When using a curved-array transducer, only segments of the needle shaft may appear.
Needle size and angle
Use a 17-gauge to 25-gauge needle (recommended). Enhancement results can depend on the type and brand
of needle used. For more information, consult the medical literature on needle visibility in ultrasound-guided
procedures.
You can angle the needle up to 50° from the transducer surface as shown in Figure 4-3 on page 39. Beyond
50°, the needle may be less enhanced.
WARNING
To avoid patient injury when using a multi-angle bracket, make sure that the same
angle is selected (A, B, or C) on both the bracket and the ultrasound system.

SNP subcontrols
When Steep Needle Profiling technology is on, additional controls are available:
L/R Flip flips the affected area (the outline) horizontally on the image. For reorienting the entire image, use
the orientation control. See “2D controls” on page 31.
Shallow, Medium, or Steep sets the outline’s sloped edge, which is indicated by a dotted line. The current
selection is highlighted.
Linear transducer: Use whichever setting best provides a perpendicular intersection with the dotted
line. Within the enhancement area, the more perpendicular that a linear structure is to the dotted line,
the more it is enhanced. Similarly, the less perpendicular (and more parallel) that a linear structure is to
the dotted line, the less it is enhanced.
Curved array transducer: For a linear structure angled 30° or less from the transducer surface, use
Shallow for best enhancement. For a linear structure angled 30-40°, use Medium. For a linear structure
angled 40° or greater, use Steep.
Off turns off SNP. Temporarily turning off SNP can help you identify artifacts and other structures not of
interest.
Note If Steep Needle Profiling technology is on, the MB control is unavailable.

Avoid setting the gain too high when using Steep Needle Profiling technology, as unnecessarily high gain can
cause artifacts in the image. Also, respiratory and cardiac movement in the image may cause bright pulsating
artifacts.

Imaging modes and exams available by transducer
WARNINGS
To prevent misdiagnosis or harm to the patient, understand your system’s
capabilities prior to use. The diagnostic capability differs for each transducer,
exam type, and imaging mode. In addition, transducers have been developed
to specific criteria depending on their physical application. These criteria
include biocompatability requirements.
To avoid injury to the patient, use only an Ophthalmic (Oph) when performing
imaging through the eye. The FDA has established lower acoustic energy limits
for ophthalmic use. The system will not exceed these limits only if the Oph
exam type is selected.
The transducer you use determines which exam types are available. In addition, the exam type you select
determines which imaging modes are available.
To select a transducer
1 Tap Transducer.
The menu showing the current active transducer appears.
2 If another transducer is connected, you can change to that one by tapping Switch.

perform general calculations as well as calculations specific to an exam type.
Measurements are performed on frozen images. For references used, see “References on
page 75
Measurements
You can perform basic measurements in any imaging mode. Options available depend on
your configuration, transducer, and exam type.
You can perform basic measurements in any imaging mode and can save the image with the
measurements displayed. Except for the M Mode HR measurement, the results do not
automatically save to a calculation and the patient report. To save measurements as part of
a calculation, you can first begin a calculation and then measure. For more information, see
“To save a measurement to a calculation and patient report” on page 57.
Working with calipers
Most measurements are performed using calipers, often in pairs, that you position by
dragging. In distance and area measurements, results are based on the calipers’ positions
relative to each other, and appear at the bottom of the screen. The results update
automatically as you reposition the calipers. In trace measurements, the results appear after
you complete the trace.
You can use either the touchpad or the touchscreen to move the calipers. You can adjust the
position of the active caliper at any time. The active caliper is highlighted in yellow. On the
touchpad, you can toggle between the calipers by tapping .
The number and type of calipers that appear on the screen depends on the measurement
type you have chosen. There are three types of calipers available:
56 Chapter 5
Distance
Measures the straight-line distance between the two calipers. After selecting a distance measurement, two
calipers appear on the scr
een. Drag the calipers to either side of the structure you want to measure.
Ellipse
Measures the circumference and surface area of an ellipse. After selecting an ellipse measurement, an
ellipse with thr
ee calipers appears on the screen. Drag the calipers to define the size, position, and angle of
the ellipse.
Trace
Measures the circumference and surface area of a shape you define. After selecting a trace measurement, a
single caliper appears on the screen. Move the caliper to the start of the trace, lift your finger to set the
location, and then drag the caliper to trace the shape.
You can have multiple sets of calipers and can switch from one set to another, repositioning them as needed.
(The calipers available depend on the number and type of measurements already performed.) Each set shows
the measurement result. A measurement is complete when you finish moving its calipers.
Note For a reliable measurement, accurate placement of calipers is essential.

Measurement accuracy
The measurements provided by the system do not define a specific physiological or
anatomical parameter. Rather, the measurements are of a physical property such as distance
for evaluation by the clinician. The accuracy values require that you can place the calipers
over one pixel. The values do not include acoustic anomalies of the body.
The 2D linear distance measurement results are displayed in centimeters with one place past
the decimal point, if the measurement is ten or greater; two places past the decimal point, if
the measurement is less than ten.
The linear distance measurement components have the accuracy and range shown in the
following table.

d. The circumference accuracy is defined as the greater of the lat
eral or axial accuracy and by the following equation:
% tolerance = (

76 Chapter 6
Sources of measurement errors
In general, two types of errors can be introduced into the measurement:
Acquisition Error
Includes errors introduced by the ultrasound system electronics relating to signal acquisition, signal
conversion, and signal processing for display. Additionally, computational and display errors are introduced
by the generation of the pixel scale factor, application of that factor to the caliper positions on the screen,
and the measurement display.
Algorithmic Error
The error introduced by measurements, which are input to higher order calculations. This error is associated
with floating-point versus integer-type math, which is subject to errors introduced by rounding versus
truncating results for display of a given level of significant digit in the calculation.
Measurement publications and terminology
The following sections list the publications and terminology used for each calculation result.
Terminology and measurements comply with AIUM published standards.

The gestational age calculated by your FUJIFILM SonoSite system does not match
the age in the aforementioned reference at the 20.0 cm and 30.0 cm abdominal
circumference (AC) measurements. The implemented algorithm extrapolates the
gestational age from the slope of the curve of all table measurements, rather than
decreasing the gestational age for a larger AC measurement indicated in the

Use of an ultrasound system is defined as the physical interaction among
the operator, the ultrasound system, and the transducer.
When using an ultrasound system, as with many similar physical activities,
you may experience occasional discomfort in your hands, fingers, arms,
shoulders, eyes, back, or other parts of your body. However, if you
experience symptoms such as constant or recurring discomfort, pain,
throbbing, aching, tingling, numbness, burning sensation, or stiffness,
promptly refer to a qualified health professional. Such symptoms can be
linked with musculoskeletal disorders (MSDs). MSDs can be painful and
may result in potentially disabling injuries to the nerves, muscles, tendons,
or other parts of the body. Examples of MSDs include carpal tunnel
syndrome and tendonitis.
WARNING
While researchers are not able to definitively answer many questions about MSDs,
there is a general agreement that certain factors are associated with their
occurrence including: preexisting medical and physical conditions, overall health,
equipment and body position while doing work, frequency of work, duration of
work, and other physical activities that may facilitate the onset of MSDs

The SonoSite Edge II ultrasound system contains an IEEE 802.11 transmitter that utilizes the ISM frequency
bands from 2.412 to 2.484GHz and implements two methods of transmission:
IEEE 802.11b with Complimentary Code Keying (CCK), Differential Quarternary Phase Shift Keying (DQPSK),
and Differential Binary Phase Shift Keying (DBPSK) at 16 dB
IEEE 802.11g with Orthogonal Frequency Division Multiplexing (ODFM) at 13 dBm
Cautions
Medical electrical equipment requires special precautions regarding EMC and
must be installed and operated according to these instructions. Portable and
mobile RF communications equipment can affect the ultrasound system.
Electromagnetic interference (EMI) from other equipment or interference sources
could result in performance disruption of the ultrasound system. Evidence of
disruption may include image degradation or distortion, erratic readings,
equipment ceasing to operate, or other incorrect functioning. If this occurs, survey
the site to determine the source of disruption, and take the following actions to
eliminate the source(s).
Turn equipment in the vicinity off and on to isolate disruptive equipment.
Relocate or re-orient interfering equipment.
Increase distance between interfering equipment and your ultrasound system.
Manage use of frequencies close to ultrasound system frequencies.
Remove devices that are highly susceptible to EMI.
Lower power from internal sources within facility control (such as paging
systems).
Label devices susceptible to EMI.
Educate clinical staff to recognize potential EMI-related problems.
Eliminate or reduce EMI with technical solutions (such as shielding).
Restrict use of personal communicators (cell phones, computers) in areas with
devices susceptible to EMI.
Share relevant EMI information with others, particularly when evaluating new
equipment purchases which may generate EMI.
Purchase medical devices that comply with IEC 60601-1-2 EMC Standards.
Do not stack other equipment on the ultrasound system or use other equipment
in close proximity and adjacent to the ultrasound system. If stacking or using other
equipment in close proximity is unavoidable, then you must observe the system to
verify normal operation.
113
Electrostatic discharge
Caution
Electrostatic discharge (ESD), or static shock, is a naturally occurring
phenomenon. ESD is common in conditions of low humidity, which can be
caused by heating or air conditioning. ESD is a discharge of the electrical energy
from a charged body to a lesser or non-charged body. The degree of discharge
can be significant enough to cause damage to a transducer or an ultrasound
system. The following precautions can help reduce ESD: anti-static spray on
carpets, anti-static spray on linoleum, and anti-static mats.
WARNINGS
Unless following ESD precautionary procedures, do not connect to or touch (with
body or hand-held tools) pins (contacts) of connectors that have the ESD
Sensitive Devices label:

Figure 9-1 The transducer connector is an example of an electrostatically-
sensitive device.
If the symbol is on a border surrounding multiple connectors, the symbol pertains
to all connectors within the border.
ESD precautionary procedures include the following:
All staff involved must receive training about ESD, including the following at a
minimum: an explanation of the ESD warning symbol, ESD precautionary
procedures, an introduction to the physics of electrostatic charge, the voltage
levels that can occur in normal practice, and the damage that can occur to
electronic components if equipment is touched by an individual who is
electrostatically charged (IEC 60601-1-2, section 5.2.1.2 d).
Prevent the buildup of electrostatic charge. For example, use humidification,
conductive floor coverings, nonsynthetic clothing, ionizers, and minimizing
insulating materials.
Discharge your body to earth.
Use a wrist strap to bond yourself to the ultrasound system or to earth.
Separation distance
The SonoSite SII ultrasound system is intended for use in an electromagnetic environment in which radiated

CHAPTER 10
Acoustic Output
This chapter contains information required by regulatory agencies, including information
about the ALARA (as low as reasonably achievable) principle, the output display standard,
acoustic power and intensity tables, and other safety information. The information applies
to the ultrasound system, transducer, accessories, and peripherals.
ALARA principle
ALARA is the guiding principle for the use of diagnostic ultrasound. Sonographers and other
qualified ultrasound users, using good judgment and insight, determine the exposure that
is as low as reasonably achievable.There are no set rules to determine the correct exposure
for every situation. The qualified ultrasound user determines the most appropriate way to
keep exposure low and bioeffects to a minimum, while obtaining a diagnostic examination.
A thorough knowledge of the imaging modes, transducer capability, system setup and
scanning technique is necessary. The imaging mode determines the nature of the
ultrasound beam. A stationary beam results in a more concentrated exposure than a
scanned beam, which spreads that exposure over that area. The transducer capability
depends upon the frequency, penetration, resolution, and field of view. The default system
presets are reset at the start of each new patient. It is the scanning technique of the qualified
ultrasound user along with patient variability that determines the system settings
throughout the exam.
The variables that affect the way the qualified ultrasound user implements the ALARA
principle include patient body size, location of the bone relative to the focal point,
attenuation in the body, and ultrasound exposure time. Exposure time is an especially useful
variable, because the qualified ultrasound user can control it. The ability to limit the
exposure over time supports the ALARA principle.
Applying the ALARA principle
The system imaging mode selected by the qualified ultrasound user is determined by the
diagnostic information required. 2D imaging provides anatomical information; CPD imaging
provides information about the energy or amplitude strength of the Doppler signal over
time at a given anatomical location and is used for detecting the presence of blood flow;
Color imaging provides information about the energy or amplitude strength of the Doppler
signal over time at a given anatomical location and is used for detecting the presence,
130 Chapter 10
velocity, and direction of blood flow; Tissue Harmonic Imaging (THI) uses higher received frequencies to
reduce clutter, artifact, and improve resolution on the 2D image. Understanding the nature of the imaging
mode used allows the qualified ultrasound user to apply the ALARA principle.
Prudent use of ultrasound requires that patient exposure to ultrasound be limited to the lowest ultrasound
output for the shortest time necessary to achieve acceptable diagnostic results. Decisions that support
prudent use are based on the type of patient, exam type, patient history, ease or difficulty of obtaining
diagnostically useful information, and potential localized heating of the patient due to transducer surface
temperature.
The system has been designed to ensure that temperature at the face of the transducer will not exceed the
limits established in Section 42 of EN 60601-2-37: Particular requirement for the safety of ultrasound medical
diagnostic and monitoring equipment. See “Transducer surface temperature rise” on page 136. In the
event of a device malfunction, there are redundant controls that limit transducer power. This is accomplished
by an electrical design that limits both power supply current and voltage to the transducer.
The sonographer uses the system controls to adjust image quality and limit ultrasound output. The system
controls are divided into three categories relative to output: controls that directly affect output, controls that
indirectly affect output, and receiver controls.
Direct controls
The system does not exceed a spatial peak temporal average intensity (ISPTA) of 720 mW/cm
2
for all imaging
modes. (For either the Ophthalmic or Orbital exam, the acoustic output is limited to the following values: ISPTA
does not exceed 50 mW/cm
2
; TI does not exceed 1.0, and MI does not exceed 0.23.) The mechanical index (MI)
and thermal index (TI) may exceed values greater than 1.0 on some transducers in some imaging modes. One
may monitor the MI and TI values and adjust the controls to reduce these values. See Guidelines for
reducing MI and TI” on page 131. Additionally, one means for meeting the ALARA principle is to set the MI or
TI values to a low index value and then modifying this level until a satisfactory image or Doppler mode is
obtained. For more information on MI and TI, refer to BS EN 60601-2-37:2001: Annex HH.
Indirect controls
The controls that indirectly affect output are controls affecting imaging mode, freeze, and depth. The imaging
mode determines the nature of the ultrasound beam. Tissue attenuation is directly related to transducer
frequency. The higher the PRF (pulse repetition frequency), the more output pulses occur over a period of
time.
Receiver controls
The receiver controls are the gain controls. Receiver controls do not affect output. They should be used, if
possible, to improve image quality before using controls that directly or indirectly affect output.
131
Acoustic artifacts
An acoustic artifact is information, present or absent in an image, that does not properly indicate the structure
or flow being imaged. There are helpful artifacts that aid in diagnosis and those that hinder proper
interpretation. Examples of artifacts include:
Shadowing
Through transmission
Aliasing
Reverberations
Comet tails
For more information on detecting and interpreting acoustic artifacts, refer to the following reference:
Kremkau, Frederick W. Diagnostic Ultrasound: Principles and Instruments. 7th ed., W.B. Saunders Company,
(Oct. 17, 2005).
Guidelines for reducing MI and TI
The following are general guidelines for reducing MI or TI. If multiple parameters are given, the best results
may be achieved by minimizing these parameters simultaneously. In some modes changing these parameters
does not affect MI or TI. Changes to other parameters may also result in MI and TI reductions. Please note the
MI and TI values on the right side of the screen.

The system meets the output display standard for TI and provides a continuous real-time
display of TI in all imaging modes, in increments of 0.1.
The TI consists of three user-selectable indices, and only one of these is displayed at any
one time. In order to display TI properly and meet the ALARA principle, the user selects an
appropriate TI based on the specific exam being performed. FUJIFILM SonoSite provides a
copy of
AIUM Medical Ultrasound Safety, which contains guidance on determining which
TI is appropriate. Refer to
“Related guidance documents on page 136.
135
MI and TI output display accuracy
The accuracy result for the MI is stated statistically. With 95% confidence, 95% of the measured MI values will
be within +18% to -25% of the displayed MI value, or +0.2 of the displayed value, whichever value is larger.
The accuracy result for the TI is stated statistically. With 95% confidence, 95% of the measured TI values will be
within +21% to -40% of the displayed TI value, or +0.2 of the displayed value, whichever value is larger. The
values equate to +1dB to -3dB.
A displayed value of 0.0 for MI or TI means that the calculated estimate for the index is less than 0.05.
Factors that contribute to display uncertainty
The net uncertainty of the displayed indices is derived by combining the quantified uncertainty from three
sources: measurement uncertainty, system and transducer variability, and engineering assumptions and
approximations made when calculating the display values.
Measurement errors of the acoustic parameters when taking the reference data are the major source of error
that contributes to the display uncertainty. The measurement error is described in Acoustic measurement
precision and uncertainty” on page 167.

136 Chapter 10
The displayed MI and TI values are based on calculations that use a set of acoustic output measurements that
were made using a single reference ultrasound system with a single reference transducer that is representative
of the population of transducers of that type. The reference system and transducer are chosen from a sample
population of systems and transducers taken from early production units, and they are selected based on
having an acoustic output that is representative of the nominal expected acoustic output for all transducer/
system combinations that might occur. Of course every transducer/system combination has its own unique
characteristic acoustic output, and will not match the nominal output on which the display estimates are
based. This variability between systems and transducers introduces an error into displayed value. By doing
acoustic output sampling testing during production, the amount of error introduced by the variability is
bounded. The sampling testing ensures that the acoustic output of transducers and systems being
manufactured stays within a specified range of the nominal acoustic output.
Another source of error arises from the assumptions and approximations that are made when deriving the
estimates for the display indices. Chief among these assumptions is that the acoustic output, and thus the
derived display indices, are linearly correlated with the transmit drive voltage of the transducer. Generally, this
assumption is very good, but it is not exact, and thus some error in the display can be attributed to the
assumption of voltage linearity.

Acoustic output measurement
Since the initial use of diagnostic ultrasound, the possible human biological effects (bioeffects) from
ultrasound exposure have been studied by various scientific and medical institutions. In October 1987, the
American Institute of Ultrasound in Medicine (AIUM) ratified a report from its Bioeffects Committee (Bioeffects
Considerations for the Safety of Diagnostic Ultrasound, J Ultrasound Med., Sept. 1988: Vol. 7, No. 9
Supplement). The report, sometimes referred to as the Stowe Report, reviewed available data on possible
effects of ultrasound exposure. Another report, Bioeffects and Safety of Diagnostic Ultrasound, dated January 28,
1993, provides more current information.
The acoustic output for this ultrasound system has been measured and calculated in accordance with
Acoustic Output Measurement Standard for Diagnostic Ultrasound Equipment” (NEMA UD2-2004), and
“Standard for Real-Time Display of Thermal and Mechanical Acoustic Output Indices on Diagnostic Ultrasound
Equipment” (NEMA UDe3-2004).
In Situ, derated, and water value intensities
All intensity parameters are measured in water. Since water does not absorb acoustic energy, these water
measurements represent a worst case value. Biological tissue does absorb acoustic energy. The true value of
the intensity at any point depends on the amount, type of tissue, and the frequency of the ultrasound passing
through the tissue. The intensity value in the tissue, In Situ, has been estimated by using the following formula:
In Situ= Water [e
-(0.23alf)
]

where:
In Situ = In Situ intensity value
Water = Water intensity value
e = 2.7183
a = attenuation factor (dB/cm MHz)
Attenuation factor (a) for various tissue types are given below:
brain = 0.53
heart = 0.66
kidney = 0.79
liver = 0.43
muscle = 0.55
l = skinline to measurement depth in cm
f = center frequency of the transducer/system/mode combination in MHz
Since the ultrasonic path during the exam is likely to pass through varying lengths and types of tissue, it is
difficult to estimate the true In Situ intensity. An attenuation factor of 0.3 is used for general reporting
purposes; therefore, the In Situ value commonly reported uses the formula:
In Situ (derated) = Water [e
-(0.069lf)
]
Since this value is not the true In Situ intensity, the term derated” is used to qualify it.
The maximum derated and the maximum water values do not always occur at the same operating conditions;
therefore, the reported maximum water and derated values may not be related by the In Situ (derated)
formula. For example: a multi-zone array transducer that has maximum water value intensities in its deepest
zone, but also has the smallest derating factor in that zone. The same transducer may have its largest derated
intensity in one of its shallowest focal zones.
Tissue models and equipment survey
Tissue models are necessary to estimate attenuation and acoustic exposure levels In Situ from measurements
of acoustic output made in water. Currently, available models may be limited in their accuracy because of
varying tissue paths during diagnostic ultrasound exposures and uncertainties in the acoustic properties of
soft tissues. No single tissue model is adequate for predicting exposures in all situations from measurements
made in water, and continued improvement and verification of these models is necessary for making exposure
assessments for specific exam types.
A homogeneous tissue model with attenuation coefficient of 0.3 dB/cm MHz throughout the beam path is
commonly used when estimating exposure levels. The model is conservative in that it overestimates the In Situ
acoustic exposure when the path between the transducer and site of interest is composed entirely of soft
139
tissue. When the path contains significant amounts of fluid, as in many first and second-trimester pregnancies
scanned transabdominally, this model may underestimate the In Situ acoustic exposure. The amount of
underestimation depends upon each specific situation.
Fixed-path tissue models, in which soft tissue thickness is held constant, sometimes are used to estimate
In Situ acoustic exposures when the beam path is longer than 3 cm and consists largely of fluid. When this
model is used to estimate maximum exposure to the fetus during transabdominal scans, a value of 1 dB/
cm MHz may be used during all trimesters.
Existing tissue models that are based on linear propagation may underestimate acoustic exposures when
significant saturation due to non-linear distortion of beams in water is present during the output
measurement.
The maximum acoustic output levels of diagnostic ultrasound devices extend over a broad range of values:
A survey of 1990-equipment models yielded MI values between 0.1 and 1.0 at their highest output settings.
Maximum MI values of approximately 2.0 are known to occur for currently available equipment. Maximum
MI values are similar for real-time 2D and M Mode imaging.
Computed estimates of upper limits to temperature elevations during transabdominal scans were obtained
in a survey of 1988 and 1990 pulsed Doppler equipment. The vast majority of models yielded upper limits
less than 1° and 4°C (1.8° and 7.2°F) for exposures of first-trimester fetal tissue and second-trimester fetal
bone, respectively. The largest values obtained were approximately 1.5°C (2.7°F) for first-trimester fetal
tissue and 7°C (12.6°F) for second-trimester fetal bone. Estimated maximum temperature elevations given
here are for a “fixed pathtissue model and are for devices having I
SPTA
values greater than 500 mW/cm
2
.
The temperature elevations for fetal bone and tissue were computed based on calculation procedures
given in Sections 4.3.2.1-4.3.2.6 in “Bioeffects and Safety of Diagnostic Ultrasound” (AIUM, 1993).
Acoustic output tables
The acoustic output tables, starting with Table 10-6, and ending with Table 10-34, indicate the acoustic
output for the system and transducer combinations with a TI or MI equal to or greater than one. These tables
are organized by transducer model and imaging mode. For a definition of terms used in the tables, refer to
“Terms used in the acoustic output tables” on page 166.

averaging the scanned data together to improve overall image quality
and, in parallel, reducing noise and artifacts.
Tissue Doppler
Imaging
A pulsed wave Doppler technique used to detect myocardial motion.
thermal index (TI) The ratio of total acoustic power to the acoustic power required to raise
tissue temperature by 1°C under defined assumptions. See Acoustic
Output” on page 129 for a more complete description of TI.
TIB (bone thermal
index)
A thermal index for applications in which the ultrasound beam passes
through soft tissue and a focal region is in the immediate vicinity of
bone.
TIC (cranial bone
thermal index)
A thermal index for applications in which the ultrasound beam passes
through bone near the beam entrance into the body.
TIS (soft tissue
thermal index)
A thermal index related to soft tissues.
Tissue Harmonic
Imaging
Transmits at one frequency and receives at a higher harmonic
frequency to reduce noise and clutter and improve resolution.
transducer A device that transforms one form of energy into another form of
energy. Ultrasound transducers contain piezoelectric elements, which
when excited electrically, emit acoustic energy. When the acoustic
energy is transmitted into the body, it travels until it encounters an
interface, or change in tissue properties. At the interface, an echo is
formed that returns to the transducer, where this acoustic energy is
transformed into electrical energy, processed, and displayed as
anatomical information.
variance Displays a variation in Color Doppler flow imaging within a given
sample. Variance is mapped to the color green and is used to detect
turbulence.
