Safety Standards
According to the American Institute of Ultrasound in Medicine (AIUM) Official
Statement of the Clinical Safety of Diagnostic Ultrasound (March 1993):
Diagnostic ultrasound has been in use since the late 1950s. Given its known benefits
and recognized efficacy for medical diagnosis, including use during human
pregnancy, the American Institute of Ultrasound in Medicine herein addresses the
clinical safety of such use: No confirmed biological effects on patients or instrument
operators caused by exposure at intensities typical of present diagnostic ultrasound
instruments have ever been reported. Although the possibility exists that such
biological effects may be identified in the future, current data indicate that the benefits
to patients of the prudent use of diagnostic ultrasound outweigh the risks, if any, that
may be present.
