Abstract: Systems and methods for estimating time-dependent voltages that are induced in electrophysiological monitoring systems by magnetic field gradients generated during a magnetic resonance imaging (“MRI”) scan are provided. The gradient-induced voltages are subsequently removed from signals acquired with the electrophysiological monitoring system during an MRI scan. As an example, the electrophysiological monitoring system can include an electrocardiography (“ECG”) system, an electroencephalography (“EEG”) system, an electromyography (“EMG”) system, a voltage device tracking (“VDT”) system, and so on. The gradient-induced voltages are estimated using a two-step procedure in which a learning algorithm is used to determine fitting parameters to be used in a model of the gradient-induced voltages. The fitting parameters are then used together with the model to extract the gradient-induced voltages from signals acquired during an MRI scan. The gradient-induced voltages can then be removed from the acquired signals.

Abstract: Described here are systems and methods for providing a non-invasive and continuous quantitative measurement of left ventricular stroke volume (“SV”) and flow volume during a magnetic resonance imaging (“MRI”) scan. In general, the method estimates quantitative measurements of SV from magnetohydrodynamic (“MHD”] voltages generated by blood flowing through the subject's vasculature while the subject is positioned in the magnetic field of an MRI system. A rapid calibration technique is provided to convert MHD voltages to estimates of blood flow, from which quantitative measurements of SV can be computed.
