Abstract
Ultrasound is being increasingly utlized as a diagnostic tool in medicine. At the pres-ent time, ultrasonic diagnostic applications is one of the most rapidly growing areas in the field of medical electronics. Its use promises to rival x rays in the near future in terms of the number of individuals exposed. Along with the increasing use of this modality comes the responsibility and need for the correct assessment of ultrasonic field parameters. The evaluation of equipment performance is important in two areas: first, in the assessment of the clinical performance of the diagnostic machine, and secondly, in evaluating the potential risk from ultrasonic exposure in relation to biological effects. The documentation of performance parameters of current diagnostic equipment is needed to provide data for epidemiological studies as well as laboratory investigations. In terms of obtaining information related to the effect that ultra-sound may have on tissue, parameters of importance include average power, average intensity? peak intensity, spatial intensity distribution, pulse repetition rate,pulse length, and ultrasonic frequency. In this area, where uncertainties exist with regard to potential biological effects, the prudent course of action is to maintain exposure levels as low as is practical consistent with obtaining the necessary diagnostic information.
