The brain structure is extracted from CT data based on thresholding and brain mask propagation. Two thresholds are determined: a high threshold excludes the high intensity bones, while a low threshold excludes air and CSF. Brain mask propagation uses the spatial relevance of brain tissues in neighbouring slices to exclude non-brain tissues with similar intensities.
