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