 == Pilot Study on BrainsFit Registration of LA Wall and Pulmonary Veins ==
+Image registration is clinically useful for the alignment of medical images acquired at different time points (among a wide variety of other uses).  For the CARMA Center, image registration of longitudinal DEMRI scans can help localize scar formation, the hallmark of ablation therapy success, or the lack thereof.  We have experimented with using the BrainsFit registration framework from Slicer to register patient scans, allowing evaluating of lesion formation and lesion gaps around the PVs, a common ablation location.
