摘要

A magnetic resonance method comprises: performing (C1) a magnetic resonance procedure on a calibration subject including an implant device; detecting (C2) a pick-up coil (PUC) signal at least during a radio frequency transmit phase of operation (C1); performing (C3) three dimensional temperature mapping of the calibration subject using a magnetic resonance sequence configured to detect any temperature change induced in any part of the implant device by operation (C1); generating (C4) an unsafe condition criterion (30) for the detected PUC signal based on correlating a PUC signal characteristic detected by operation (C2) with a temperature change detected by operation (C3); performing (M5) the magnetic resonance procedure on a subject containing an implant device; detecting (M6) a PUC signal at least during a radio frequency transmit phase of operation (M5); and monitoring (M7) for an unsafe condition indicated by the PUC signal detected in operation (M6) satisfying the unsafe condition criterion (30).
