Concerns Surrounding the Use of Diagnostic Ultrasound

.
6–2
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 order this document from the AIUM to
become more familiar with Ultrasound safety.
