摘要：
The invention relates to a correction method for correction of noise resulting from gradient artifacts in ECG signal data records recorded in a magnetic resonance device by an ECG measuring apparatus. A first correction data record is determined with a reference point of the ECG measuring apparatus located at a first position in the magnetic resonance device. An ECG signal data record is measured with the reference point of the ECG measuring apparatus located at a second position in the magnetic resonance device. A modified correction data record is specified as a function of the first correction data record and the first and second position of the reference point. The ECG signal data record is corrected based on the modified correction data record.
