Guidance of electrophysiological (EP) procedures by MRI is attractive compared with x-ray fluoroscopy because MRI has good tissue contrast and can be used to visualize arrhythmogenic regions of heterogeneous scar and healthy tissue (gray zone). The Vurtigo software presented here is designed to enhance guidance of radio-frequency (RF) ablation therapies with visualization of a prior volume roadmaps, tracked catheters and EP recordings. The open source, cross-platform, free software is extensible with plug-ins and is computationally efficient with GPU accelerated graphics and threading.
