Safety and Care
Biohazard Considerations
WARNING: Siemens makes every effort to manufacture safe and effective probes. You
must take all necessary precautions to eliminate the possibility of exposing patients,
operators, or third parties to hazardous or infectious materials. These precautions should
be considered in the use of any application that may indicate the need for such care, for
example, when scanning patients with open wounds.
WARNING: To eliminate the possibility of exposing patients, operators, or third parties
to hazardous or infectious materials, always dispose hazardous or infectious materials
according to local, state, and regional regulations.
WARNING: Probe Sheaths: There have been reports of severe allergic reactions to
medical devices containing latex (natural rubber). Health care professionals are advised
to identify latex sensitive patients and to be prepared to treat allergic reactions promptly.
For additional information in the U.S.A., refer to FDA Medical Alert MDA91-1.
WARNING: Ultrasound energy is transmitted more effectively through water than through
tissue. When using a standoff device of any kind, for example, a waterpath or gel pad, the
actual mechanical and thermal indices, MI and/or TI, may be higher than indicated in the
output display on the ultrasound system.
The assessment of the biological effects of diagnostic ultrasound on humans is a subject of
ongoing scientic research. This ultrasound system, and all diagnostic ultrasound procedures,
should be used for valid reasons, for the shortest possible period of time, and at the lowest
mechanical and thermal indices necessary to produce clinically acceptable images.
According to the principles of ALARA (As Low As Reasonably Achievable), the acoustic output
should be the lowest level required to satisfactorily perform the examination.
The ultrasound imaging system complies with the standards of the American Institute of
Ultrasound in Medicine (AIUM) and the National Electrical Manufacturers Association (NEMA),
the guidelines of the United States Food and Drug Administration (FDA) and the standards
of the International Electrotechnical Commission (IEC) in terms of safety and acoustic output
levels. The ultrasound output levels are stated to permit the user to critically evaluate the
ultrasound system settings in the event of new research ndings being announced.

Acoustic Output
WARNING: Ultrasound procedures should be used for valid reasons, for the shortest
period of time, and at the lowest mechanical/thermal index setting necessary to produce
clinically acceptable images.
NOTE: For ultrasound systems distributed in the United States of America, refer to
the Medical Ultrasound Safety ultrasound education program brochure produced by
the AIUM that is shipped with the system. This document explains the interaction of
ultrasound and tissue, the possibilities and mechanisms of bioeffects, and it explains
the terms used to describe acoustic output.
The ultrasound energy, frequency levels, and scanning times employed by the ACUSON
Freestyle have not been associated with harmful effects. Nevertheless, it is advisable to
minimize the patient’s exposure to ultrasound energy. This prudent use can be accomplished
by following the ALARA (As Low as Reasonably Achievable) Principle, and by operating the
system in a manner that reduces patient exposure to ultrasound energy. Acoustic Output
tables for the ACUSON Freestyle are provided below.
The acoustic output for the ACUSON Freestyle has been measured and calculated in
accordance with the “Acoustic Output Measurement Standard for Diagnostic Ultrasound
Equipment” (NEMA UD2-2004), and the “Standard for Real-Time Display of Thermal and
Mechanical Acoustic Output Indices on Diagnostic Ultrasound Equipment” (NEMA UD3-2004.)
Safety and Care
ALARA / Prudent Use
Prudent use of ultrasound requires that patient exposure to ultrasound energy be limited to the
lowest output for the shortest period of time needed to obtain acceptable diagnostic results.
Techniques include:
1. Keep exams as brief as possible, consistent with diagnostic requirements.
2. Select the appropriate transducer for the patient body type and exam type in order to
optimize imaging results.
3. Use overall gain or dynamic range or post processing settings, which have no effect on
output, to optimize the image and obtain diagnostic results.
4. In general, as shown in the Acoustic Output Tables, Color Flow Doppler mode will have
higher output levels than B-Mode (2D). Keep this in mind when scanning. New studies
default to B-Mode.

Safety and Care
Acoustic Output: Global Maximum Values
No system/transducer combination is capable of exceeding either a Thermal Index (TI) of 1.0 or
a Mechanical Index (MI) of 1.0, so, in accordance with relevant standards (NEMA UD3-2004),
the system does not display MI or TI. The table below, Global Maximum Values, provides the
mean of the global maximum of acoustic output values. The terms are described below.
Table entries have been obtained with the same operating conditions that create the maximum
value.
Uncertainties associated with the values derive from transducer and system variability,
measurement variability, and engineering approximations for real-time calculations.
Measurement precision and uncertainty for quantities used to calculate the values in the table
are 30% for intensity and 15% for MI.
Maximum surface temperatures are in accordance with IEC 60601-2-37.

Accuracies
Measurement Accuracies
The ACUSON Freestyle may be used to provide measurements and calculations derived from
ultrasound images. The quantied image data may be used along with other clinical information
to assist a physician in making a patient diagnosis.
The sole reliance on diagnostic ultrasound data to make a clinical diagnosis is not
recommended. Numerous factors related to the accuracy of ultrasound image data must be
taken into account. This section describes some of these factors. Measurement accuracies are
also inuenced by operator experience, scanning technique, interpreting physician experience,
and the technical difculty of the patient. Many of these variables are not associated with the
ACUSON Freestyle system. This limits the ability to fully specify the clinical accuracy of the
measurements and calculations provided by the system.
Accuracy by Transducer Type
All transducer types have been veried for measurement accuracy in the modes appropriate to
each measurement type.
Because the moderate transducer frequency range of the system, measurement accuracies for
the system are not expected to vary signicantly based on transducer used.
Safety and Care
Accuracy of Primary Measurements
All reported accuracies are +/– one-half the least signicant digit.
Distance
The system assumes that the speed of sound in tissue is 1540 meters per second and that
this speed is homogeneous in all tissues. The diagnostic ultrasound literature states that
differences in the speed of sound in the body do exist because of the differing tissue types. In
Clinical Sonography – A Practical Guide, (2nd Edition, Roger C. Sanders, ed., Little Brown and
Company 1991) the range is cited as from 1500 to 1600 meters per second. These differences
would produce an inaccuracy of up to +/– 4%.
The distance measurements on the system are veried using an AIUM standard phantom
with a uid having an acoustic speed of approximately 1540 meters per second at room
temperature. The accuracy of this measurement is +/– 5%. The maximum range of this
measurement is 24 cm (dependent on the probe).
Area
The accuracy of the area measurement is +/– 10%.
The maximum range of this measurement is 733 cm2 (dependent on the probe).

Safety and Care
Potential Sources of Measurement Error During Scanning
The table below identies potential sources of measurement error that may occur during
scanning. Awareness of these sources can help you avoid errors they may cause.
Potential Source
of Error Explanation of Error
Patient Variability The technical difculty of patients in ultrasound imaging varies widely.
Greater care must be taken with technically difcult patients to obtain
the best images possible with the optimal transducer and system
control settings.
Operator Variability The skill, care, and experience of the person conducting the scan is
one of the most critical factors in obtaining accurate measurements.
Operator training should be consistent with the recommendations of the
appropriate professional medical societies.
Speed of Sound The image processing and measurement algorithms of diagnostic
ultrasound assume that the speed of sound in body tissue is 1540
meters per second. Different body tissues have different sound speeds.
In soft tissue there is approximately a 2% error; this may be as high as
5%, especially if fatty tissue is present in the area being measured.
Doppler Alignment When performing Doppler scans, try to align the Doppler sample as
close to parallel as possible.
Screen Pixel
Resolution
WARNING
The display screen provided in the ACUSON Freestyle system is
comprised of a rectangular array of square picture elements (pixels).
Measurement pixel resolution is assumed to be +/– one pixel. The
maximum potential error of this resolution accuracy is 0.4%
Occasionally, a pixel or a group of pixels of the display may enter a fault
condition and become stuck in an on or off position. If stuck pixels occur
at a place where a measurement value is displayed, it could cause the
operator to misread the result. Pixels stuck in the on position may be
detected by looking at the screen with a dark background. Pixels stuck
in the off position will show up as dark against a bright video image. You
should periodically examine your system for stuck pixels and be aware
of this potential condition when reading measurements. If you believe
your system has stuck pixels, contact your Service Representative.

Electrical Safety
WARNING: Explosion Hazard. Possible explosion hazard if used in the presence of
ammable anesthetics.
WARNING: To avoid electric shock, use a protective earth connection to connect the
ultrasound system to the AC Mains power supply. The protective earth connection
ensures that the mains circuit breaker will disconnect the power supply in the event of a
short circuit.
WARNING: To ensure grounding reliability, only connect the system to a hospital-grade
power outlet.
WARNING: The AC Mains power connector plug for the ultrasound system is a three
prong grounded plug (in the U.S.A.) and should never be adapted to any two prong (non
grounded) outlet, either by modifying the plug or by using an adapter. In the U.S.A.,
proper grounding requires the AC Mains power connector plug to be plugged into a
hospital grade power outlet.
WARNING: Risk of re. Replace fuse as marked.
Safety and Care
WARNING: To avoid electrical shock, never modify the ultrasound system AC Mains
power connector plug, as doing so may overload your facility’s power circuits. To ensure
grounding reliability, connect the system only to an equivalent outlet.
WARNING: To avoid electrical shock, never use equipment or an AC Mains power
cord that shows signs of wear or tampering, or that has a ground plug which has been
bypassed by using an adapter.
WARNING: Equipment connected to the ultrasound system and in the patient zone
must be powered from a medically isolated power source or must be a medically isolated
device. Equipment powered from a non isolated source can result in chassis leakage
currents exceeding safe levels. Chassis leakage current and patient leakage current
created by an accessory or device connected to a non isolated outlet may add to the
chassis leakage current of the ultrasound system.
WARNING: Using an extension cord or multi socket outlet setup to provide power to the
ultrasound system, or to the system’s peripheral devices may compromise the system
grounding and cause your system to exceed leakage current limits.
WARNING: To avoid electrical shock and damage to the ultrasound system, power
off and unplug the equipment from the AC Mains power outlet before cleaning and
disinfecting.
WARNING: To prevent excessive leakage current from contacting the patient, do not
touch a user-accessible connector on the system while touching or scanning the patient.
User-accessible connectors include connectors such as the USB connectors, and any
other audio, video, or data transmission connectors.
ACUSON Freestyle User Manual 2-17

Safety and Care
WARNING: Connecting peripheral devices to accessory outlets on the ultrasound system
effectively creates a medical electrical system, resulting in a reduced level of safety.
WARNING: No modication of this equipment it allowed.
WARNING: Do not remove system covers. There are no operator serviceable parts
inside. Refer servicing to qualied personnel.
WARNING: To avoid the risk of electrical shock and re hazard, inspect the system
probes and console on a regular basis for any damage to the enclosure, controls,
connectors or display, and do not use if damaged. Electrical safety tests must also be
performed at regular intervals as specied by local safety regulations, or as needed.
WARNING: To avoid the risk of electrical shock do not touch the probe battery recharging
contacts on the system console.
CAUTION: To avoid the possibility of static shock and damage to the ultrasound system,
avoid the use of aerosol spray cleaners on the monitor screens.
CAUTION: Do not use spray cleaners on the ultrasound system, as this may force
cleaning uid into the system and damage electronic components. It is also possible for
the solvent fumes to build up and form ammable gases or damage internal components.
CAUTION: Do not pour any uid onto the ultrasound system surfaces, as uid seepage
into the electrical circuitry may cause excessive leakage current or system failure.
CAUTION: To ensure proper grounding and leakage current levels, it is the policy of
Siemens to have an authorized Siemens representative or Siemens approved third party
perform all on board connections of documentation and storage devices to the ultrasound
system.
CAUTION: To avoid the risk of electrical shock and re hazard, inspect the system
probes and console on a regular basis for any damage to the enclosure, controls,
connectors or display, and do not use if damaged. Electrical safety tests must also be
performed at regular intervals as specied by local safety regulations, or as needed.
EMC Note: Proximity to sources of strong electromagnetic elds, such as radio
transmitter stations or similar installations may lead to interference visible on the monitor
screen. However, the device has been designed and tested to withstand such interference
and will not be permanently damaged.
CAUTION: Total system chassis risk current should not exceed 100 microamps.
CAUTION: Do not position the system to make it difcult to disconnect the power cable
connector/plug.
CAUTION: If the probe overtemp or probe battery overtemp message appears, the
system will stop imaging and the image will be frozen. Unfreeze will not function until the
overtemp condition terminates.

within 1.5 meters (1.83 meters [6 feet] in Canada and the U.S.A.) of a patient (beyond the
perimeter of the bed — examination table, treatment surface, and the like) and extending
vertically 2.29 meters (7.5 feet) above the oor, unless the device receives power from an
isolation transformer that meets medical safety standards.
The ultrasound system supports a maximum of two documentation or storage devices
connected to the system. Siemens recommends that you power off each device whenever the
system is powered off.
CAUTION: Any on-board peripheral devices must be installed by an authorized Siemens
representative or by a Siemens-approved third party. Devices installed by other people
will be at the user’s risk and may void the system warranty.
In order to fulll EN 60601-1-1 and IEC 60601-1-1 (Medical Electrical Equipment, Part 1:
General Requirements for Safety) requirements, connection of peripheral equipment to your
ultrasound system much adhere to one of the following conditions:
■ The peripheral equipment itself is a medical device approved according to EN 60601-1
and IEC 60601-1, or
■ Non-medical peripheral equipment approved according to any other EN or IEC standard
(EN XXXXX or IEC XXXXX, e.g., equipment complying with EN 60348 and IEC 60348, EN
60950 and IEC 60950, etc.) must use the following setup for connection:
– The peripheral equipment is located at least 1.5 meters (1.83 meters [6 feet] in Canada and
the U.S.A.) outside the patient environment and extending vertically 2.29 meters (7.5 feet)
above the oor. A patient environment is dened as the area in which medical examination,
monitoring, or treatment of the patient takes place (examination table, treatment surface, and
the like).
– The peripheral equipment is connected to a main outlet outside the patient environment but
still within the same room as the ultrasound system
– The peripheral equipment is connected to the ultrasound system using isolation adapters.

Important Information for Maintaining Data Integrity
CAUTION: To prevent corruption of data stored on inserted media, do not interrupt the
exporting process. Do not delete exported patient data from the local database until the
exporting process is complete and the inserted media is determined to be full (or no more
exporting is planned for the inserted media).
■ To prevent the loss of data that results from power failures and other system “down”
occurrences, you must archive important data, such as patient records, onto a network or
an external recording medium, such as a USB, or DICOM storage device.
■ Loss of data is to be expected and its retrieval is not normally possible under the following
conditions: loss of power to the ultrasound system, hard disk failure, CPU failure, system
lockup, and other similar causes.
■ Should an abnormal system shutdown occur, retrieval of data not saved to the hard disk or
not archived to an external recording media is not normally possible.
■ An abnormal system shutdown occurs if you do not power off the ultrasound system using
the power on/off key located on the control panel. Other examples of abnormal system

Good Ergonomic Practices
WARNING: The operation of an ultrasound system may to linked to musculoskeletal
disorders (MSDs).
In ultrasound imaging, ergonomics may be dened as the physical interaction between the
operator, the system, and the transducer, in the course of conducting exams. It is important for
the operator of the system to practice good ergonomic techniques to reduce the risk of injury.
This chapter is intended to provide guidelines to help you work more comfortably in order to
possibly reduce the risk of musculoskeletal disorders.
When using an ultrasound system, as with many similar physical activities, you may experience
occasional discomfort in your hands, ngers, arms, shoulders, eyes, neck, back, or other parts
of your body. If you experience symptoms such as constant or recurring discomfort, pain,
throbbing, aching, tingling, numbness, burning sensation, or stiffness, you should promptly
consult a qualied health professional. These may be symptoms of MSD. MSDs can be painful
and may result in potentially disabling injuries to the nerves, muscles, tendons, joints, or other
parts of the body. Examples of MSDs include carpal tunnel syndrome and tendonitis.
Steps you can take to guard against discomfort while scanning, or the risk of MSD are
described here. It is also recommended that you consult the guidelines of professional medical
societies concerned with ultrasound.
Interrupt Scanning
Interrupt scanning frequently, using breaks to rest and give soft tissue a chance to recuperate
from the strained positions and repetitive movements of examinations.
While scanning, avoid maintaining the same body position for extended periods of time, by
moving and varying head, neck, body, arm, and leg positions.
Positioning
Avoid bending or stooping.
Adjust the position of the ACUSON Freestyle such that viewing or reaching the controls does
not require strained or awkward body positions.
Whenever possible, use an adjustable chair with good back support, and adjust chair height to
promote good body posture. If possible, adjust the height of the patient bed to optimize body
posture.
Maintain a comfortable and balanced body position with minimal stress on your joints,
minimizing bending and twisting.
Keep elbows close to your side and relax your shoulders in a level position.
Hand and Wrist
Do not grasp the transducer with excessive force; hold it as lightly as possible.
Minimize the amount of pressure applied when pressing the transducer against the patient.
Avoid or minimize bending your wrist.
Exercise and Stretching
Targeted exercises and stretching may help avoid the risk of MSDs. Consult with a qualied
health professional to dene a program suited to your needs and practices.

Using the Probe
About the Probe
Probe Orientation
The probe index marker is the side of the probe where the probe on/off symbol is located. This
corresponds to the ACUSON “a” symbol next to the image display. The probe model numbers,
such as “L8-3” also serve as index markers. For transducers in non-cardiac applications, the
normal and default location of the on-screen index marker symbol is to the left of the image.

Probe Controls
Functions in the real-time Control Bar can be adjusted or selected using the controls on the
probe. These controls include the slider, the two circular buttons, and the two buttons in the
middle of the probe.
The slider mimics the function of the large Rotary knob on the console, moving the selection of
the active item in the real-time control knob:
■ To move the highlight up the list, push upward on the slider, away from the transducer face.
■ To move the highlight down, push downward on the slider, toward the transducer face.
The button towards the rear of the probe (away from the transducer) represents Plus, the
button towards the front of the probe (towards the transducer) represents Minus. These mimic
the functions of the inner Rotary knob on the console.
■ Plus corresponds to clockwise rotation of the knob.
■ Minus corresponds to counterclockwise rotation of the knob.
Locking and Unlocking the Probe
Before using the probe controls, you may have to unlock these functions on the probe if you
unchecked the Enable Probe Key and Slider selection in the SETUP / SYSTEM / ADMIN page.
