x 1 ABSTRACT Many applications of MRI are facilitated by segmenting the volume spanned by the imagery into the various tissue types that are present. Intensity-based classication of MR images has proven to be problematic, even when advanced techniques such as non-parametric multi-channel methods are used. A persistent diculty has been accommodating the spatial intensity inhomogeneities that are due to the equipment. This paper describes a statistical method that uses knowledge of tissue… CONTINUE READING
