IEC TS 62556:2014是适用于高强度治疗性超声（HITU）设备的技术规范。它指定了量化字段的相关参数；相对较低输出水平下的测量方法，以及将其外推到更高治疗水平领域的方法；旁瓣和焦前最大值的一些考虑；以及与不同结构和几何形状的HITU传感器相关的参数，包括非聚焦、带或不带透镜聚焦、准直、发散和会聚传感器、多元件传感器、扫描传感器和多个源。本技术规范旨在支持IEC 60601-2-62中给出的超声波测量要求。这些规范将用于质量保证、安全测试和HITU系统临床性能相关通信的标准化。 在可能的情况下，本技术规范包含其他相关标准的规范。 本技术规范不适用于其他标准涵盖的以下类型的设备:碎石机（见IEC 61846）；外科设备（见IEC 61847）；和物理治疗设备（见IEC 61689）。

IEC TS 62556:2014 is a technical specification applicable to high intensity therapeutic ultrasound (HITU) devices. It specifies the relevant parameters for quantifying the field; the measurement methods at relatively low output levels and methodology for extrapolating these to higher therapeutic level fields; some considerations of sidelobes and pre-focal maxima; and 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: lithotripters (see IEC 61846); surgical equipment (see IEC 61847); and physiotherapy devices (see IEC 61689).
