Description: This paper introduces an automated medical image segmentation algorithm which can be used to locate volumetric objects such as brain tumor in Magnetic Resonance Imaging (MRI) images. The algorithm is novel in that it deals with MRI slices (or images) as a three dimension (3D) object as a whole. All the processes of segmentation are done in 3D space. First, it removes noisy voxels with 3D nonlinear anisotropic filtering. The filtering well preserves the intensity distribution continuity in all three directions as well as smoothes noisy voxels. Second, it uses a novel deformable surface model to segment an object from the MRI. A dynamic gradient vector flow is used in forming the surface model. Experiments have been done on segmenting tumors from real MRI data of human head. Accurate 3D tumor segmentation has been achieved.
