ISO/TC 150/SC 6/JWG 2 - JWG between ISO/TC 150/SC 6 and IEC/SC62B: Effects of magnetic resonance imaging on active implantable medical devices

This document provides guidance for some methods that could be used to evaluate the sources of uncertainty. It is important to note that there are many legitimate methods for analyzing the overall uncertainty and that the methods in this document are illustrative only.

ISO/TS 10974:2018 is applicable to implantable parts of active implantable medical devices (AIMDs) intended to be used in patients who undergo a magnetic resonance scan in 1,5 T, cylindrical (circular or elliptical cross-section) bore, whole body MR scanners operating at approximately 64 MHz with whole body coil excitation. NOTE 1 Requirements for non-implantable parts are outside the scope of this document. The tests that are specified in this document are type tests that characterize interactions with the magnetic and electromagnetic fields associated with an MR scanner. The tests can be used to demonstrate device operation according to its MR Conditional labelling. The tests are not intended to be used for the routine testing of manufactured products. NOTE 2 Modification of these tests for particular device types is left to particular product committees. NOTE 3 Other interested parties, such as device manufacturers, regulatory agencies, and particular product committees, are responsible for setting specific compliance criteria and determining risk. NOTE 4 Safety requirements for MR scanners can be found in IEC 60601‑2‑33. NOTE 5 The scope is limited to AIMDs that do not use sensing functions or to AIMDs that are programmed not to use sensing functions to affect therapy delivery during an MR scan.

ISO/TS 10974:2012 is applicable to implantable parts of active implantable medical devices (AIMDs) intended to be used in patients who might undergo a magnetic resonance scan in 1,5T, cylindrical bore, whole body MR scanners for imaging the hydrogen nucleus. The tests that are specified in ISO/TS 10974:2012 are type tests intended to be carried out on samples of a device to characterize interactions with the magnetic and electromagnetic fields associated with an MR scanner. ISO/TS 10974:2012 contains test methods that are applicable to a broad class of AIMDs for the purpose of evaluating device operation against several hazards.
