Patent ID: 8831328

Claim:
A method for segmenting a brain image into a plurality of regions comprising at least a cerebrospinal fluid (CSF) region, wherein the brain image comprises intensity values at respective points and wherein the method comprises the operations of: (a) defining an initial intensity range; (b) extracting from the image a plurality of points with intensity values within the intensity range; (c) identifying a subset of the extracted points forming a spatially connected region of a maximum size; (d) generating a histogram of the intensity values of the subset of the extracted points; (e) obtaining a significance parameter characterizing the generated histogram; (f) at least once varying the intensity range and repeating operations (b)-(e) to maximize the value of the significance parameter; (g) estimating a limit for the intensity values in the CSF region as an end of the varied intensity range; and (h) using the estimated limit for the intensity values in the CSF region in a process of segmenting the image.
