Embodiment

[0048] The resolution of the sequence template image and the heart image to be segmented in this embodiment is 512*512.

[0049] Such as figure 1 As shown, the present invention proposes a kind of registration-based CT image whole heart automatic segmentation system, and its workflow is as follows:

[0050] In the first step, the input module 100 inputs a cardiac CT sequence image template and cardiac CT images to be segmented.

[0051] In the second step, the input module 100 transmits the cardiac CT template image to the segmentation module 200, segments the various parts of the heart on the CT sequence image template, marks each part with a marker, creates a Label image, and transmits it to the transformation module 500 ; The Label image can be applied to all segmentation instances without repeated production.

[0052] In the third step, the input module 100 transmits the cardiac CT sequence image template and the cardiac CT image to be segmented to the rough registration...

Abstract

The invention discloses a registration-based CT (Computed Tomography) image total heart automatic cutting system. In the system, registration is applied to cutting to realize automatic cutting of a total heart by using similarity of heart CTs of different individuals. The system comprises the following modules: an input module, a cutting module, a rough registration module, a fine registration module, a conversion module and an output module. The system can realize automatic cutting of the total heart and can be used for simultaneously cutting a plurality of heart chambers.

Description

technical field [0001] The invention relates to a medical image segmentation system, in particular to a registration-based CT image whole-heart automatic segmentation system. Background technique [0002] Medical image segmentation is a process of extracting regions of interest, which is a key step before 3D visualization of medical images. Cardiac segmentation can segment the various parts of the heart, thereby providing a large amount of anatomical information for clinical diagnosis, and providing a basis for preoperative planning of cardiac surgery and cardiac interventional surgery. Calculating the volume of each segmented chamber can also provide quantitative information for cardiac function evaluation. [0003] At present, the segmentation of medical images can be divided into manual segmentation, semi-automatic segmentation and automatic segmentation. Manual segmentation means that doctors use clinical knowledge to outline the area of ​​interest on medical images, w...
