Fusion of multi-contrast late enhancement information and voltage signal of electroanatomical map. (a) LGE images using the MCLE sequence (or steady-state T1*) were processed using a fuzzy clustering algorithm to classify each pixel as infarct (green), healthy myocardium (purple), or gray zone (yellow). (b) SSFP-derived meshes were overlaid with voltage amplitude information obtained from the MR-Guided endocardial mapping procedure, resulting in an EAVM (color coded as per color bar). (c) After the procedure, EP meshes were fused with the MCLE-derived images.
