Abstract :
We present an algorithm to automatically register magnetic resonance (MR) and positron emission tomography (PET) slices of the human brain. Our algorithm is an integrated approach. We simultaneously segment the brain in both modalities and register the slices. The algorithm does not attempt to remove the skull from the MR image, but rather uses “templates” constructed from PET images to locate the boundary between the brain and the surrounding tissue in the MR images. The PET templates are a sequence of estimates of the boundary of the brain in the PET images
