 == Goal==
-Goal is to accommodate basic RECIST assessment for breast cancer (Response Evaluation Criteria In Solid Tumors). (RECIST is a set of published rules that define when cancer patients improve ("respond"), stay the same ("stable") or worsen ("progression") during treatments).
+Goal is to accommodate basic RECIST assessment for cancer treatment.
-* Determine features that currently exist in Slicer
+Specifically for volumetric analysis:
-* Develop features that don't
+* perform linear measurements
-* Provide a framework that knits features together in a comfortable workflow.
+* perform volumetric measurements

+* create a subvolume of target breast for both pre and post treatment timepoints: try to make these two subvolumes match as closely as possible. Ron uses 2-fold oversampling.
 * mask out background
-* perform histogram matching (normalization across both subvolumes)
+* perform histogram matching with "threshold at mean" checked
-* registration
+* Ran diffeomorphic demons on post, took 3 hours, with nice results
