Description of PD IEC TS 63070:2019 2019

This document is applicable to ultrasonic equipment designed for the medical field of application. It covers both diagnostic and therapeutic (physiotherapy and HITU) equipment.

This document describes transducer evaluation by the infrared imaging technique using a split TMM-phantom for qualitative and quantitative estimation of temperature distributions in tissue-mimicking material, resulting from absorption of ultrasound and from heating of the transducer itself.

This document also describes a method to measure transducer-surface temperature, while the transducer is driven under the still-air condition.

NOTE 1 When the transducer is in contact with tissue-mimicking material, the heating of the transducer itself depends on the actual efficiency of the transducer, on the specific conditions for thermal transfer to or from the tissue-mimicking material, and on the transmitting/receiving electronic circuits, such as a switching circuit or pre-amplifier in some cases.

NOTE 2 The test objects specified in this document are for the measurement of temperature rise and not for the determination of thermal index, which is, by definition in IEC 62359:2010 and IEC 62359:2010/AMD1:2017, an algebraic combination of acoustical field quantities and therefore is not a physically measurable quantity.
