Objective / Background
We seek to align the pre-operative CT&MRI with the post-operative CT.
Keywords
MRI, CT, IGT, intra-operative, liver, cryoablation, change detection, non-rigid registration
Input Data
- reference/fixed : 0.57 x 0.57 x 5 , 512 x 512 x 37 voxels
- moving: 0.57 x 0.57 x 5 mm, 512 x 512 x 33 voxels
- moving: 1.56 x 1.56 x 2.5 mm, 256 x 256 x 88
- moving: 1.56 x 1.56 x 6 mm, 256 x 256 x 36
Methods
Registration Results
This case is currently unsolved with standard Slicer 3.6 technology. Special/custom modifications to registration modules (SlicerIGT Registration) are under way and will be incorporated into future releases.

Discussion: Registration Challenges
- large differences in FOV
- strong differences in image contrast between MRI & CT
- contrast enhancement and pathology and treatment changes cause additional differences in image content
- we have strongly anisotropic voxel sizes with much less through-plane resolution
