Ultrasonics. Pulse-echo scanners. Techniques for calibrating spatial measurement systems and measurement of system point-spread function response | Status: Current

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.
