Abstract
Systems, method and apparatus in which some embodiments of automatic segmentation of a liver parenchyma from multiphase contrast-enhanced computed-tomography images includes analyzing an intensity change in the images belonging to the different phases in order to determine the region-of-interest of the liver, thereafter segmenting starting from the region-of-interest and incorporating anatomical information to prevent oversegmentation, and thereafter combining the information of all available images.
