We have developed a technique to fuse ablation lesions and cardiac anatomy from MRI with ablation maps from an electro-anatomical mapping system. We present the fused data results for a patient undergoing treatment for atrial flutter in the XMR setting. (a-c) Enhancing areas (green) seen in context of anatomical images (greyscale). Overlaid are the ablation points (red) from the XMR EAMS. (d) Ablation points (red) mapped onto the right-heart surface model derived from the gadolinium-enhanced MRA images.
