核磁共振环境中医疗设备及其他设备安全性标识的标准实施规程

[中文适用范围]： 本国际标准适用于可能用于磁共振（MR）环境中的物品标记实践。 本实践的目的是标记可能被带入MR环境的物品，并建议标记中应包含的信息。 本标准规定了通过术语和图标对MR环境中使用的物品进行永久性标记。 MR图像伪影不被视为性能问题，因此不在本国际标准实践中讨论（参见X1.5）。 以SI单位表示的值应被视为标准。本标准不包括其他测量单位。 本标准不旨在解决与其使用相关的所有安全问题（如果有）。使用本标准的用户有责任在使用前建立适当的安全和健康实践，并确定法规限制的适用性。 [外文原描述]： IEC 62570:2014 applies to the practice of marking of items that might be used in the magnetic resonance (MR) environment. The purpose of this practice is to mark items that might be brought into the MR environment and to recommend information that should be included in the marking. The standard specifies the permanent marking of items, which are used in an MR environment, by means of terms and icons. MR image artifacts are not considered to be a performance issue and so are not addressed in this international standard practice. IEC 62570 is integrating the unmodified text of ASTM F2503-13. It has been developed by subcommittee 62B: Diagnostic imaging equipment, of IEC technical committee 62: Medical equipment in medical practice, in collaboration with ASTM.
