Patients with AMIDs are exposed to a significant safety hazard during MRI, as the RF excitation couples to the elongated metallic structures of the AIMD resulting in an unwanted heating of tissue. Temperature measurements are the standard method for heating tests of implants to ensure patient safety during MRI exams. Temperature sensors with a significant size compared to the samples influence the RF absorption of energy and can distort the temperature distribution. MR thermometry can provide a non-invasive 2D alternative.
