Problems solved by technology

During the process of removing adjacent tissues, if there is a metal object in the heart, such as a pacemaker, or the detected object has undergone open heart surgery such as heart bypass, when segmenting the CT image of the detected object’s heart, metal Objects and the artifacts they cause will have a serious impact on segmentation, making the obtained 3D image of the heart imprecise, for example, including part of the rib or part of the lung area, or the segmented heart area is incomplete, etc. Subsequent coronary diagnosis affects

Abstract

The invention provides a heart CT image processing method and device and a non-transient computer readable storage medium. The heart CT image processing method comprises the steps of reconstructing aheart CT image of a detected object based on projection data of a heart region of the detected object; processing voxel points with voxel values within a first threshold range in the heart CT image toobtain a first image, wherein the first threshold range is limited by CT values of ametal object; performing lung region segmentation on the first image to obtain a second image; performing initial heart region segmentation on the second image to obtain a third image; and performing rib removal on the third image to obtain a heart image.

Description

technical field [0001] The present invention relates to image processing, in particular to a heart CT image processing method and device, and a non-transitory computer-readable storage medium. Background technique [0002] Heart disease, especially coronary heart disease, is one of the major diseases that seriously affect human health. Early detection of atherosclerotic plaques, aneurysms and abnormal structures in coronary arteries is an important factor in the diagnosis and treatment of coronary heart disease. In the detection of coronary heart disease, it mainly depends on the three-dimensional image of the heart of the object to be detected (for example, a patient). Therefore, how to accurately obtain the three-dimensional image of the heart of the object to be detected becomes the key. [0003] The heart is located in the chest cavity and between the two lungs. In the process of obtaining a three-dimensional image of the heart, adjacent tissues around the heart, such as...
