TS 62556-2014 Ultrasonics – Field characterization – Specification and measurement of field parameters for high intensity therapeutic ultrasound (HITU) transducers and systems (Edition 1.0)
This technical specification is applicable to high intensity therapeutic ultrasound (HITU) devices@ specifying: ?C relevant parameters for quantifying the field; ?C measurement methods at relatively low output levels and methodology for extrapolating these to higher therapeutic level fields; ?C consideration of sidelobes and pre-focal maxima; ?C parameters relevant to HITU transducers of different construction and geometry@ including non-focusing@ focusing with or without lenses@ collimated@ diverging and convergent transducers@ multi-element transducers@ scanning transducers and multiple sources. This technical specification is intended to support the ultrasonic measurement requirements given in IEC 60601-2-62. These specifications would have use in quality assurance@ safety testing@ and the standardization of communications regarding the clinical performance of HITU systems. Where possible@ this technical specification incorporates specifications from other related standards. This technical specification does not apply to the following types of devices@ which are covered by other standards: ?C lithotripters (see IEC 61846); ?C surgical equipment (see IEC 61847); ?C physiotherapy devices (see IEC 61689). Throughout this technical specification SI units are used. In the specification of certain parameters@ such as beam-areas and intensities@ it may be convenient to use decimal multiples or sub-multiples. For example@ beam-area may be specified in cm2 and intensities in W/cm2 or mW/cm2.
