Patent ID: 8521258

Claim:
A correction method for correcting an interference due to a gradient injection in an ECG signal data record recorded in a magnetic resonance device by an ECG measuring device, comprising: capturing movement of the ECG measuring device as a function of time with a movement capturing unit; determining a first correction data record when the ECG measuring device is in a first position; determining a second correction data record when the ECG measuring device is in a second position wherein the first and second correction data records are determined based on a known parameter of the gradient injection comprising a current applied to a gradient coil of the magnetic resonance device; measuring the ECG signal data record with the ECG measuring device when the ECG measuring device is in a defined position; generating a modified correction data record as a function of the first correction data record and the second correction data record and the first position, the second position and the defined position of the ECG measuring device wherein the first, second and modified correction data records are determined based on estimated pulse responses; correcting the ECG signal data record based on the modified correction data record and; wherein the steps of capturing movement of the ECG measuring device, determining a first correction data record, determining a second correction data record, measuring the ECG signal data record, generating a modified correction data record and correcting the ECG signal data record are implemented in a machine that includes storage and a processing unit.
