Abstract

The invention discloses a head symmetry axis recognition method and device, a storage medium and computer equipment; the method comprises the steps: recognizing a brain tissue edge chain code and a chain code cutting point corresponding to a brain tissue region in a target head medical image, and carrying out the recognition of the brain tissue edge chain code according to the position relation between the brain tissue edge chain code and the chain code cutting point; extracting a front section upper sagittal sinus chain code and a rear section upper sagittal sinus chain code in the brain tissue edge chain codes; determining a front section candidate angular point according to the front section curvature value of each point in the front section upper sagittal sinus chain code, and determining a rear section candidate angular point according to the rear section curvature value of each point in the rear section upper sagittal sinus chain code; detecting a first position feature of the front-section candidate angular point in the front-section upper sagittal sinus chain code, determining a front-section target angular point based on the first position feature, detecting a second position feature of the rear-section candidate angular point in the rear-section upper sagittal sinus chain code, and determining a rear-section target angular point based on the second position feature; and determining a head symmetry axis corresponding to the brain tissue area according to a connecting line of the front-section target angular point and the rear-section target angular point.

Description

technical field [0001] The present application relates to the technical field of medical imaging, in particular to a head symmetry axis identification method and device, storage medium, and computer equipment. Background technique [0002] Brain diseases greatly affect the quality of life of patients, so their diagnosis and treatment are hot issues in the field of global health. The identification of the symmetry axis of the brain is an indispensable key step in the diagnosis and treatment of brain diseases. Such as cerebral hemorrhage edema, brain tumor space occupying and other diseases caused by brain midline deviation, cerebral ischemia on the left and right sides, quantitative calculation of hemorrhage volume, and prediction of brain injury caused by head radiation therapy, etc. significance. [0003] The basis for determining the symmetry axis of the brain is mainly the shape and structure of the brain. At present, the methods for identifying the symmetry axis of th...
