METHOD FOR VENTRICLE SEGMENTATION USING RADIAL THRESHOLD DETERMINATION

摘要

PURPOSE: A method for ventricle segmentation using radial threshold determination is provided to minimize user interference by dividing left ventricle of heart magnetic resonance imaging. CONSTITUTION: An initial point is detected according to the brightness value of a heart magnetic resonance image in a detecting step(S110), in which a plurality of critical points are detected. The brightness of the plurality of critical points is set by the plurality of critical value in a binarization step (S120), in which the binarization of the heart magnetic resonance image is repeatedly performed. The size of left ventricle in a binarized image in a calculation step(S130). A left ventricle domain in the magnetic resonance image is divided in a division step(S140).
