Home < Non-rigid MR-CT Image RegistrationNon-rigid Registration of Pre-procedural MRI and Intra-procedural CT for CT-guided Cryoablation Therapy of Liver Cancer Tutorial
Overview
This tutorial demonstrates how to perform a pre-operated contrast enhanced MR image to intra-procedure CT image non-rigid registration. The case study is CT-guided liver tumor cryoablation.
Clinical significants
- Non-rigid registrations desirable to compensate for liver deformation caused by patient positioning, respiratory motion, and interventional manipulation.
- A multi-modality non-rigid registration method can enhance visualization of tumor margins and location during the planning, targeting, and monitoring phases of CT imaging-guided cryoablation procedure.
Tutorial Topics / Targets
- Slicer Modules Used:
- N4ITKBiasField Correction
- Editor
- BRAINSFitIGT Registration
- Image Processing Tasks Performed:
- Intensity non-uniformly correction
- Mask generation / segmentation
- Inter-modality non-rigid image registration
- Image Data Used:
- Pre-operative abdominal MR with surface coil, showing liver
- Planning and Intra-operative CT with cryo-probe
Overview
- This tutorial will go through the following steps (in order):
- Preprocessing
- MRI mask generation
- CT mask generation
- MRI Bias Field Intensity Correction
- Registration
- MRI-CT(#1) non-rigid registration
- CT(#1)-CT(#2) affine registration
- Resampling & Fusion
