Ultrasonics. Physiotherapy systems. Field specifications and methods of measurement in the frequency range 0,5 MHz to 5 MHz. | Status: Current

1 Scope This document is applicable to ultrasonic equipment designed for physiotherapy containing an ultrasonic transducer generating continuous or quasi-continuous (e.g. tone burst) wave ultrasound in the frequency range 0,5 MHz to 5 MHz. This document only relates to ultrasonic physiotherapy equipment employing a single plane non-focusing circular transducer per treatment head, producing static beams perpendicular to the face of the treatment head. This document specifies:

• • methods of measurement and characterization of the output of ultrasonic physiotherapy equipment based on reference testing methods;
• • characteristics to be specified by manufacturers of ultrasonic physiotherapy equipment based on reference testing methods;
• • guidelines for safety of the ultrasonic field generated by ultrasonic physiotherapy equipment;
• • methods of measurement and characterization of the output of ultrasonic physiotherapy equipment based on routine testing methods;
• • acceptance criteria for aspects of the output of ultrasonic physiotherapy equipment based on routine testing methods.

Therapeutic value and methods of use of ultrasonic physiotherapy equipment are not within the scope of this document. Ultrasonic physiotherapy equipment using ultrasound in the frequency range from 20 kHz to 500 kHz is dealt with in IEC 63009.
