Patent ID: 8340384

Claim:
A method of segmenting a cerebral hemorrhage site in a medical image of a head, said method comprising: segmenting, using a data processing unit, an internal region of a skull bone in the medical image; segmenting, using the data processing unit, a possible cerebral hemorrhage region out of the internal region of the skull bone by segmenting a region with CT values gradually changing out of the internal region of the skull bone; segmenting a region with a number of pixels larger than a predetermined number, out of the region segmented in said step of segmenting a region with CT values gradually changing; segmenting a region with a comparatively large CT value out of the region segmented in said step of segmenting a region with a number of pixels larger than a predetermined number; and segmenting a region with CT values gradually changing out of the region segmented in said step of segmenting a region with a comparatively large CT value; and determining a cerebral hemorrhage site within the possible cerebral hemorrhage region.
