Magnetic Resonance Imaging (MRI) is increasingly becoming the preferred diagnostic and interventional imaging modality for a variety of diseases. Despite the increasing clinical merit, practical implementation of these procedures in the clinic is oftentimes limited due to the high risk associated with these patient groups and the subsequent need for advanced physiological monitoring for each patient to be cleared for MRI imaging and interventional workflows. The presented method for beat-to-beat SV and continuous aortic flow monitoring within the MRI bore based on Magnetohydrodynamic Voltages (VMHD) induced onto 12-lead Electrocardiograms (ECG), enables MR imaging and MRI-guided interventional procedures for these patients.
