Abstract

A procedure for segmentation of intracranial tissues, including cerebrospinal fluid surrounding the brain, cortical and subcortical gray matter, and white matter, in a T-1-weighted magnetic resonance image of the brain, has been developed. The proposed method utilizes information from the histogram of pixel intensities of the intracranial image. Based on this information, an unsupervised K-means clustering procedureseparates various tissue regions. Information about the approximate location of anatomical regions within the intracranial space is used todetect ventricles and the caudate nuclei. First a description and justification for tile procedure is presented. Then the performance of the procedure is evaluated by analysis of variance. In conclusion, the results of applying this procedure to 31 healthy subjects are presentedand future improvements are discussed. (C) 1997 Wiley-Liss, Inc.
