Acoustic Output
Bioeffects
Concerns Surrounding the Use of Diagnostic Ultrasound
During a diagnostic ultrasound examination, high frequency
sound penetrates and interacts with tissue in and around the
area of anatomy to be imaged. Only a small portion of this sound
energy is reflected back to the probe for use in constructing the
image while the remainder is dissipated within the tissue. The
interaction of sound energy with tissue at sufficiently high levels
can produce biological effects (aka bioeffects) of either a
mechanical or thermal nature. Although the generation of
bioeffect is intentional with therapeutic ultrasound, it is generally
undesired in diagnostic applications and may be harmful in
some conditions.
NOTE: The American Institute of Ultrasound in Medicine has published
a document entitled "Medical Ultrasound Safety". This three
part document covers Bioeffects and Biophysics, Prudent Use
and Implementing ALARA.
Ultrasound users should read the AIUM to become more familiar
with Ultrasound safety. A copy of this document is included as
part of the documentation CD (5268173-200).

Measurement Precision and Uncertainty
Precision and measurement uncertainty of the system used to
measure the acoustic output is provided in the following table.
These values are determined in accordance with Section 6.4 of
the Standard for Real-Time Display of Thermal and Mechanical
Acoustic Output Indices on Diagnostic Ultrasound Equipment,
rev 2 AIUM/NEMA 2004, and the Acoustic Output Measurement
Standard for Diagnostic Ultrasound Equipment, rev 3 NEMA

FDA Acoustic Output Data
Maximum output summary
The following tables list the typical maimum acoustic output
levels achievalbe with LOGIQ C5/C5 PRO for all probes and
operational modes. It is intended that this is information be
useful in making ALARA decisions and selecting the most
appropriate probe for the application. In accordance with US
FDA Guidelines, the overall maximum acoustic SPTA intensity
for LOGIQ C5/C5 PRO is limited to 720 mW/cm
limited to 1.9. Modes for which TI does not exceed 0.1 are
indicated by <0.1. TI is limited to 6.0.
Table 1-2 shows all of the probes’ operating modes. The
following pages contain probe acoustic output tables for those
noted in Table 1-2.
