 * Slicer was used to import the DICOM sequence and export 10 individual volumes. The sequences module combined with volume rendering within Slicer provided exploratory qualatative analysis of the wrist kinematics.

 * 3D segmentation of individual bones was solved via level-set segmentation within [http://www.itksnap.org/pmwiki/pmwiki.php itkSNAP]. Preliminary tests with Slicer GrowCut were not satisfactory due to highly non-isotropic voxels, but more tests will be necessary to explore new advanced features within "Segment Editor".

-The goal of this project is to analyze wrist kinematics from a dynamic MRI sequence. Challenges include segmentation of wrist bones from relatively low resolution MRI with anisotropic voxels, and joint spatiotemporal modeling of extracted bones as a multi-object complex.
+* The clinical goal of this project is the use of dynamic MRI (instead of static series of 3D CT done so far) to explore 3D carpal dynamics to detect kinematic wrist abnormalities in diagnosis/staging/management, to study carpal motion in health/disease, and to evaluate results after surgery
