Describes: - parameters related to thermal and non-thermal exposure aspects of diagnostic ultrasonic fields; - methods for the determination of an exposure parameter relating to temperature rise in theoretical tissue-equivalent models, resulting from absorption of ultrasound; and - methods for the determination of an exposure parameter appropriate to certain non-thermal effects. Applies to medical diagnostic ultrasound fields.
