 <h3>Approach, Plan</h3>
@@ Line 41: / Line 41: @@
 For this experiment, we are interested in registering structural MRI of the chest before and after ablation surgery.  During the ablation procedure, a catheter is inserted to burn heart tissue in the atria demonstrating abnormal electrical activity.  The ablation creates scar tissue, which does not conduct electricity, allowing the heart to return to a normal beating pattern.  As a result of the procedure, the atrial wall shows a vastly different contrast than the scan taken before surgery.  In addition, there are geometric differences between structures present in the two images.  For these reasons, this is a challenging non-linear registration problem.
