- Scope
- This standard specifies the measurement method for the frequency characteristics of ultrasonic diagnostic and monitoring equipment in the frequency range of 0.5MHz ~ 15MHz. This standard applies to all types of ultrasonic diagnostic equipment and ultrasonic monitoring equipment operating in continuous wave, quasi-continuous wave or pulse wave states. These equipment can be equipped with single-chip transmit-receive probes and dual single-chip transmit-retract split probes. Multi-element plum blossom probes, mechanical fan sweep probes, linear probes, convex array probes and phased array probes, etc.
