scope:

This International Standard describes methods of calibrating the spatial measurement facilities and point-spread function of ultrasonnic imaging equipment in the ultrasonic frequency range 0,5 MHz to 15 MHz. This standard is relevant for ultrasoninc scanners based on the pulse-echo principle of the types listed below: - mechanical sector scanners; - electronic phased-array sector scanners; - electronic liniar-array scannars; - electronic curved-array sector scanners; - water-bath scanners based on any of the above four scanning mechanisms; - 3D-volume reconstruction systems.
