5. Image fusion / registration
• Co-registration of image data (CT, MRI, PET/CT, …) is essential
for image-guided RT.
• Linear / rigid registration:
-
Landmark – based
-
Mutual information
• Non-linear / deformable registration methods:
-
Volume / feature-based algorithms
-
Optical flow methods
-
Demon’s algorithm
