Mutual information based registration of brain images
Karol Kuczyński, Paweł Mikołajczak · Journal of Medical Informatics & Technologies · 2002
Various medical imaging techniques (CT, MRI, PET, etc.) provide information about different properties of the examined tissues. Since this information is often of a complementary nature, in medical diagnostics, planning and evaluating of surgical and radiotherapeutical procedures it is desired to use integrated useful data from different modality images. The integration task is not trivial due to unlike patient’s spatial orientation, datasets’ resolutions and voxel intensity profiles. The goal of registration (matching, alignment) process is, given two images of the same object, to find a spatial transformation T, that relates them. The next step is a fusion of the registered datasets.
