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

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.<\/p>\n

This document also describes a method to measure transducer-surface temperature, while the transducer is driven under the still-air condition.<\/p>\n

\n

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.<\/p>\n<\/blockquote>\n

\n

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.<\/p>\n<\/blockquote>\n
