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.
