This technical report provides guidance on the practical measurement of the acoustic output of various types of medical ultrasonic equipment in the frequency range 0,5 MHz to 15 MHz based on the use of hydrophones.
It gives simplified procedures and guidelines for the measurement of the acoustic output of medical ultrasonic equipment.
Procedures for correcting for limitations caused by the use of hydrophones with finite bandwidth and finite active element size are also given.
