Pilot Study on BrainsFit Registration of LA Wall and Pulmonary Veins

Examples

Good LA Wall and PV Registration	Septal Misregistration	PV Misregistration
An example of generally good registration of both the LA wall and PVs on a patient's pre- and 3 month post-ablation DEMRI scans (affine and rigid registration via BrainsFit module).	An example of the pre- and post-ablation images from the same patient that were registered (affine and rigid) with the BrainsFit module. The registration was good except along the septal surface (arrows).	Affine and rigid registration (BrainsFit module) of the same patient's pre- and post-ablation scans improved the alignment of the PVs, but sufficient overlap of the corresponding PV structures was not achieved.
