Abstract
A method and a magnetic resonance tomography (MRT) system are provided. The MRT system includes a controller configured to store a transmit vector that is established on a local-coil-specific basis. The transmit vector, for a specific local coil, indicates with which amplitudes and phases, transmit elements of the local coil may be controlled by a transmit device. The controller is configured to initiate a patient-specific calibration measurement on a patient to generate patient-specific calibration data representing a field distribution. The controller is also configured to determine deviations in the patient-specific calibration data from the stored transmit vector established on a local-coil-specific basis. The patient-specific calibration data is generated in the patient-specific calibration measurement on the patient and represents a field distribution. An imaging MRT measurement is not allowed if deviations exceed a threshold value, but is otherwise performed and is monitored by a monitoring device.
