Flow Diagram CMFreg/slicer Method. This method uses two different programs ITK-Snap and 3D Slicer. T1 and T2 DICOM files are initially opened and converted to GIPL using ITK-Snap. Segmentations then are created using the GIPL.GZ files for both pre and post treatment scans using the 3D Slicer to construct 3D volumetric label maps. Surface models are created after using the T1 scan and segmentation in 3D Slicer to re-orient the head [1]. Once the T1 scan has been reoriented, the registration (superimposition) of the T2 image upon the T1 image is carried out on the segmented cranial base. Then T1 and T2 images are landmarked using ITK-Snap and new models are created to measure the absolute differences between the pre and post-treatment images
