Abstract :
The aim of this work is to develop and test an automatic image registration method for CT and MR of the pelvis which does not require external landmarks, and works with MR slices in any orientation (e.g., axial, coronal and saggital). By combining chamfer matching with automatic segmentation methods, a fast (a few minutes) and accurate (about 2 mm) method for CT-MR registration is obtained. However, failures of the matching method due to local minima cannot always be avoided. In such cases, manual adjustment of the starting position is sufficient to obtain a good match
