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 tobe imaged. Only a smallportion 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.

Acoustic Output Data
Maximum output summary
The following tables list the typical maimum acoustic output
levels achievalbe with LOGIQ 7/LOGIQ 7 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 7/LOGIQ 7 Pro is limited to 720 mW/cm2and MI is
limited to 1.9. Modes for which TI does not exceed 0.1 are
indicated by <0.1.
• The accuracy of acoustic output table of this manual : +0%/-
50%
• Accuracy of TI and MI is ±50%.
Table 1-1 shows all of the probes’ operating modes. The
following pages contain probe acoustic output tables for those
noted in Table 1-1.
