Abstract

The invention relates to a heart image processing method in a medical image. The method comprises the steps that the three-dimensional medical image set of a cross-section is input; the template imageset of the cross-section is acquired; the input three-dimensional medical image set is compared with the acquired template image set; a first medical image element, which demonstrates a heart start layer on the cross-section, of the three-dimensional medical image set and a second medical image element, which demonstrates a heart stop layer on the cross-section, of the three-dimensional image setare determined; and according to the relationship among a first template image element which demonstrates the heart start layer, a second template image element which demonstrates the heart stop layer, and a third template image element which demonstrates a heart marker layer in the template image set, a third medical image element which demonstrates the heart marker layer on the cross-section inthe three-dimensional medical image set is determined. According to the method provided by the invention, the heart marker layer can be accurately located, and the heart position can be accurately located.

Description

technical field [0001] The invention belongs to the technical field of image recognition and processing, in particular to a method for processing heart images in medical images. Background technique [0002] The heart is a key organ of the human cardiovascular system. Modern medical imaging techniques are able to provide structural and functional information of the heart. Among them, CT (Computed Tomography) has fast imaging speed, high resolution and large amount of information, and is an important means of heart examination. Segmentation of heart regions based on medical images, such as CT images, plays an important role in the diagnosis and treatment of cardiovascular diseases. At present, scholars at home and abroad have proposed many segmentation algorithms for certain anatomical structures in the heart, and these segmentation algorithms are mainly aimed at the segmentation of atrium and ventricle. For applications such as cardiac surgery navigation, interventional t...
