Magnetohydrodynamic voltages (VMHD), induced from the interaction between blood flow and an external magnetic field, have been shown to be a useful physiological monitoring metric. VMHD was first observed in intra-MRI ECGs and can be a predictor of blood flow. An adaptive filtering method was developed to try and obtain better ECGReal by utilizing an isolated VMHD source, and a Gadolinium choke was created to better adapt physiological monitoring technology for use in MRI. A smartphone-enabled portable device was prototyped to induce and measure VMHD outside of the MRI, which offers a low cost, easy-to-use alternative to current methods of peripheral blood flow quantification. Finally, a phantom setup was constructed to explore contributing factors to induced VMHD in a more controlled environment. Future work will continue to explore the different factors of VMHD and test the developed technologies on larger patient groups.
