1.1本试验方法表征了被动植入物（在不提供电力或外部电源的情况下工作的植入物）在磁共振（MR）图像中产生的失真和信号损失伪影。不包括任何未确定为MR Safe或MR条件性的内容。 1.2以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 ====意义和用途====== 5.1本试验方法提供了在标准扫描条件下产生的图像伪影的量化测量。 5.2本试验方法仅适用于已确定为MR安全或MR有条件的被动植入物。

1.1 This test method characterizes the distortion and signal loss artifacts produced in a magnetic resonance (MR) image by a passive implant (implant that functions without the supply of electrical or external power). Anything not established to be MR-Safe or MR-Conditional is excluded. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. ====== Significance And Use ====== 5.1 This test method provides a quantified measure of the image artifact produced under a standard set of scanning conditions. 5.2 This test method applies only to passive implants that have been established to be MR-Safe or MR-Conditional.
