What is DD IEC/TS 62306 - Test objects for determining temperature elevation about?
DD IEC/TS 62306 is a technical specification that discusses the field characterisation for ultrasonics to determine temperature elevation in diagnostic ultrasound fields.
DD IEC/TS 62306 applies to medical diagnostic ultrasonic fields. DD IEC/TS 62306 specifically relates to the test objects which contain an embedded thermal sensor (such as a thermocouple or thermistor) although some parts may also be relevant to an alternative method of temperature determination.
The test objects are for the measurement of temperature rise and not for the determination of thermal index which is, by definition, an algebraic combination of acoustical field quantities and is therefore not a physically measurable quantity.
DD IEC/TS 62306 establishes:
The important characteristics and terminology for test objects containing an embedded thermal sensor to determine ultrasonic heating
Requirements for defining types of test objects for specific applications
Examples of design features that will ensure that the performance specifications are achieved
Validation procedures
General test methods for using test objects to determine standardised temperature rises
