摘要:
The invention relates to a correction method for correcting interference due to gradient injections in ECG signal data records recorded in a magnetic resonance device by an ECG measuring device. A first correction data record is determined with the ECG measuring device located in a first position. A second correction data record is determined by the ECG measuring device located in a second position. An ECG signal data record is measured by the ECG measuring device located in a defined position. A modified correction data record is defined as a function of the first correction data record and the second correction data record and the first and second position and the defined position of the ECG measuring device. The ECG signal data record is corrected based on the modified correction data record.
