Abstract

The invention relates to a heart image processing method for radiotherapy accurate positioning, and the method comprises the steps: obtaining a heart image, dividing a ventricular septum into a plurality of to-be-acted regions according to the curvature of a first boundary line and a second boundary line, comparing the widths of the plurality of to-be-acted regions with a standard ventricular septum width, and obtaining a comparison result; positioning the action position of radiotherapy according to the comparison result, marking the action position, and determining the action time and the action intensity according to the difference width of the to-be-acted area exceeding the standard ventricular septum; and adjusting the marked action time and operation intensity according to the relationship between the blood flow rate and a preset standard flow rate. A heart image is acquired, the position of a ventricular septum on the heart image is determined, the heart image is marked according to the actual width and the standard width of a to-be-acted area in the ventricular septum, and information needing to be marked comprises the action position, the action time and the action intensity, so that corresponding radiotherapy is carried out.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a heart image processing method for precise radiotherapy positioning. Background technique [0002] HOCM is the most common cause of sudden death in young people. Drug treatment cannot improve the outcome of the disease. The annual mortality rate is 1.7% to 4%, and the 5-year mortality rate is 15%. The interventricular septum is located between the left and right ventricles, and the middle part of the interventricular septum is obviously convex to the right ventricle and concave to the left ventricle. Some heart diseases require surgical ablation or removal of abnormal heart tissue to achieve the purpose of treating the disease, such as abnormally hypertrophic interventricular septum in hypertrophic cardiomyopathy. Some of these abnormal myocardial tissues have special anatomical locations, and cannot be removed or eliminated by surgery or transcatheter intervention, or...
