ξ Acoustic Output and Measurement
Since the ξrst use of diagnostic ultrasound, the possible human biological eξects (bioeξects) of
ultrasound exposure have been studied by various scientiξc and medical institutions. In October
1987, the American Institute of Ultrasound in Medicine(AIUM) ratiξed a report prepared by
its Bioeξects Committee (Bioeξects Considerations for the Safety of Diagnostic Ultrasound, J
Ultrasound Med., Sept. 1988: Vol.7, No.9 Supplement), sometimes referred to as the Stowe Report,
which reviewed available data on possible eξects of ultrasound exposure. Another report, βBioeξects
and Safety of Diagnostic Ultrasoundβ, dated January 28, 1993, provides more up-to-date information.
In addition, periodically updated reports on biological eξects, results, and guidelines on safe usage
have been published by groups such as WFUMB (World Federation of Ultrasound in Medicine and
Biology), AIUM, and BMUS.
The Acoustic output for this system has been measured and calculated in accordance with the
Standard for Real-Time Display of Thermal and Mechanical Acoustic Output Indices On Diagnostic
Ultrasound Equipment (AIUM / NEMA, 2004) and the Acoustic Output Measurement Standard for
Diagnostic Ultrasound Equipment (AIUM / NEMA, 2004)
