The brain shape is deformed regionally by kinds of cerebral diseases and the degree of progress. Therefore quantitative evaluation of the deformation using MR images is effective for diagnosis of cerebral diseases. To evaluate the cerebral deformation, almost conventional methods are based on normalization of the brain shape which deforms the evaluating brain into the standardized brain. Because the...
This paper presents a fully-automatic and robust MRI segmentation method for brain tissues. The proposed method classifies the brain MRI volume to 4 classes: white matter tissue (WM), gray matter tissue (GM), cerebrospinal fluid (CSF), and the remaining tissues as non-brain tissues (NBT). We utilize the pre-segmented volumes to determine statistically the prior probability for each class, prior information...
