Gradient-Induced Voltages on 12-Lead ECGs during High Duty-Cycle MRI Sequences and a Method for Their Removal considering Linear and Concomitant Gradient Terms

PURPOSE: To restore 12-lead ECG signal fidelity inside MRI by removing magnetic-field gradient induced-voltages during high gradient-duty-cycle sequences. THEORY AND METHODS: A theoretical equation was derived, providing first- and second-order electrical fields induced at individual ECG electrode a...
