This report offers current views on exposure criteria for medical diagnostic ultrasound. Major sections of the report cover: hyperthermia and life processes; heat generation by ultrasound in mammalian tissues; experimental studies of ultrasonically produced temperature elevation and associated biological effects; the interrelationship of thermal and nonthermal ultrasonic process; intensity and power needed in diagnostic ultrasound. Appendices to the report provide background for calculations and information on approximations and assumptions employed in the report.
