 During the project week, we will discuss and prototype potential improvements to the method, which may include:
 * Organ border specification using the structure tensor (segmentation currently required)
-* Incorporate more efficient diffusion calculation schemes

 <h3>Objective</h3>
-TODO
+We are interested in registering images that contain anatomical variation between them, for example where organs slide against each other.  For example, the brain may slide against the skull due to intraoperative brain shift, the heart slides relative to the lungs throughout the cardiac cycle, and respiration induces sliding of the lungs against the chest wall or abdominal muscles against each other.  Not considering anatomical variation during image registration leads to errors that may impact clinical outcomes.
