Причина отменыThis test method characterized 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).
Formerly under the jurisdiction of Committee F04 on Medical and Surgical Materials and Devices, this test method was withdrawn in March 2022 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
Значение и использование 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.
Область применения 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.
