The ultrasound imaging system complies with the standards of the
American Institute of Ultrasound in Medicine (AIUM), the National Electrical
Manufacturer's Association (NEMA), the guidelines of the United States
Food and Drug Administration (FDA), and the guidelines 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 system settings in the event of new research findings
being announced.

Thermal Indices
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.
The ultrasound system incorporates an output display of Mechanical and
Thermal Indices
to allow you to monitor, and to limit, the amount of
ultrasound energy that is transferred to the patient.
Note: For systems distributed in the United States of America, refer to the Medical
Ultrasound Safety ultrasound education program brochure produced by the AIUM that is
included in the System Reference .
Mechanical and Thermal Indices
The system displays the Mechanical and Thermal Indices during real-time
imaging, in all imaging modes, when the Mechanical Index or the Thermal
Indices are equal to or exceed a value of 0.4.
