Non-invasive electrophysiology mapping based on affordable electrocardiogram hardware and imaging

A system for electrophysiology (EP) mapping, the system comprising:

• an x-ray imager configured to provide two-dimensional x-ray images;
• an ECG monitor;
• a red, green, blue, depth (RGBD) camera;
• an image processor configured to estimate an exterior surface of a patient from the RGBD camera, estimate a three-dimensional heart mesh, by a machine-learnt regressor trained to extrapolate three-dimensional heart surfaces from three-dimensional exteriors and a heart shadow from two-dimensional projection images, from the estimated exterior surface of the patient and a heart shadow from one or more two-dimensional x-ray images of the patient output by the x-ray imager, and generate an EP map, spatially distributed on the estimated three-dimensional heart mesh, from measurements of electrodes of the ECG monitor based on the estimated exterior surface of the patient;
• and
• a display configured to display the EP map,
• wherein the image processor is configured to generate the EP map from a reconstruction of a body surface potential map extrapolated from the measurements of the electrodes of the ECG monitor to other locations on the detected three-dimensional exterior surface and a back projection of the body surface potential map to the estimated three-dimensional heart mesh.
