范围:本国际标准适用于CT扫描仪（以下简称医用电气设备）的基本安全和基本性能。如果某一条款或子条款明确规定仅适用于医用电气设备，或仅适用于医用电气系统，则该条款或子条款的标题和内容应如此说明。如果情况并非如此，则本条款或子条款适用于医用电气设备和医用电气系统（视情况而定）。注1——另见通用标准的4.2。本文件的范围仅限于用于头部和身体的CT扫描仪，其特点是X- 射线源和成像探测器安装在环形的通用保护罩中。它包括CT扫描仪中使用的X射线发生器的安全要求，包括高压发生器与X射线管组件集成的要求。注2——先前在IEC 60601-2-7和IEC 60601-2-32中规定的X射线发生器和相关设备的要求已包含在IEC 60601-1:2005（Ed3）或本版IEC 60601-2-44中。 因此，IEC 60601-2-7和IEC 60601-2-32不属于第三版计算机断层扫描方案的一部分。

Scope:This International Standard applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of CT SCANNERS, hereafter also referred to as ME EQUIPMENT.If a clause or subclause is specifically intended to be applicable to ME EQUIPMENT only, or to ME SYSTEMS only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies both to ME EQUIPMENT and to ME SYSTEMS, as relevant.Note 1 - See also 4.2 of the general standard.The scope of this document is limited to CT SCANNERS intended to be used for both head and body characterised by an ENCLOSURE of the X-ray source(s) and imaging detector(s) in a common protective cover in the shape of a toroid. It includes safety requirements for the XRAY GENERATORS used in CT SCANNERS, including those where HIGH-VOLTAGE GENERATORS are integrated with an X-RAY TUBE ASSEMBLY.Note 2 - Requirements for X-RAY GENERATORS and for ASSOCIATED EQUIPMENT, which were previously specified in IEC 60601-2-7 and IEC 60601-2-32, have been included in either IEC 60601-1:2005 (Ed3) or this edition of IEC 60601-2-44. Therefore IEC 60601-2-7 and IEC 60601-2-32 are not part of the 3rd edition scheme for COMPUTED TOMOGRAPHY.
