ENDO- AND EPI- CARDIAL BOUNDARY DETECTION APPARATUS OF THE LEFT VENTRICLE AND METHOD THEREOF

摘要

PURPOSE: A device and method for detecting a boundary between an inner wall and an outer wall of a left ventricle are provided to set a proper brightness critical range at an image with a low contrast ratio by considering a brightness value distribution of a myocardium according to each data property. CONSTITUTION: A myocardium inner wall extracting unit(210) computes a seed position from a CT(Computed Tomography) image of a heart and extracts the boundary of an initial myocardium inner wall by using a radiation tracking method. A myocardium outer wall extracting unit(220) extracts the boundary of a myocardium outer wall from the CT image of the heart. A boundary correcting unit(230) corrects a boundary between the inner wall and the outer wall of the myocardium.
