ASTM F2182 – 11a

Work Item s – proposed revisions of this standard. This test method describes a test procedure for evaluating the RF-induced temperature rise associated with an MR procedure involving a specific frequency of RF irradiation of an implant.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. For other implantation conditions asm example, external fixation devices, percutaneous needles, catheters or tethered devices such as ablation probesmodifications of this test method are necessary.

For other implantation conditions for example, external fixation devices, percutaneous needles, catheters r2182 tethered devices such as ablation probesmodifications of this test method are necessary. Other safety issues that should be addressed include magnetically induced displacement force and torque, as well as proper device function while in various configurations in the MR environment.

It is the responsibility of the user of this standard to establish appropriate safety and v2182 practices and determine the applicability of regulatory limitations prior to use. Active view current version of standard. Link to Active This link will always route to the current Active version of the standard. These two measurements estimate the local SAR and the local additional temperature rise with the implant. Because of possible additional heating, particularly when implant dimensions approaches or exceeds one quarter of the wavelength of the RF field inside the phantom, conclusions from measurements made at one static magnetic field strength do not apply to other field f21182 and frequencies.

The combination of the test results and the computational model results may then be used to help assess the safety of a patient with the implant during an Qstm scan. The RF coil is assumed to have quadrature excitation. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The heating measurements are made twice, once with the implant and then repeated at the same location without the implant.
