Gives methods of measuring performance of real-time medical ultrasonic imaging equipment in frequency range 0,5 MHz to 15 MHz. Applies to real-time ultrasonic scanners based on pulse-echo c principle for mechanical sector, electronic phased array sector, electronic linear array, electronic curved array sector and water bath scanners.

This technical report describes methods of measuring the performance of real-time medical ultrasonic imaging equipment in the frequency range 0,5MHz to 15MHz. This report is relevant for real-time ultrasonic scanners based on the pulse-echo principle, for the types listed below:

• mechanical sector scanner;

• electronic phased array sector scanner;

• electronic linear array scanner;

• electronic curved array sector scanner;

• water-bath scanner based on any of the above four scanning mechanisms.
