Embodiment Construction
[0081] Embodiments of the present invention provide a method and device for segmenting a three-dimensional image of a heart. Considering that the heart has relatively complex morphological characteristics, that is, there is a relatively obvious boundary between the top of the heart and the surrounding adjacent tissues, while the bottom of the heart is connected to the diaphragm. Therefore, in the embodiment of the present invention, the critical layer is located first, that is, the critical layer between the top of the heart and the upper part of the heart, and the heart is divided into two parts, the upper part and the bottom part, according to this critical layer, and then each part of the heart is established segmentally. Finally, a complete three-dimensional heart model is formed by the upper heart model and the bottom heart model, and the three-dimensional image of the heart can be clearly displayed through the three-dimensional heart model.

A three-dimensional cardiac image segmentation method and apparatus are provided according to examples of the present disclosure. The method includes: searching from layers of cardiac computerized tomography CT images to obtain a layer of cardiac CT image located between a heart bottom portion and a heart upper portion as a first key layer; searching on the first key layer to obtain a boundary of the heart as a contour of the heart bottom portion, and generating a curved surface model based on the contour of the heart bottom portion and a lowest point of the heart bottom portion as a heart bottom model; searching layers of cardiac CT images above the first key layer to obtain boundaries of the heart as a contour of the heart upper portion, and generating a curved surface model based on the contour of the heart upper portion as a heart upper model.
Description
technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for segmenting a three-dimensional heart image. Background technique [0002] According to statistics, coronary heart disease (full name: coronary atherosclerotic heart disease) is one of the main diseases that seriously affect human health, and the incidence rate has been increasing year by year in recent years. Therefore, early detection and diagnosis of coronary heart disease, early treatment is particularly important. In the early detection of coronary heart disease, it mainly depends on the three-dimensional image of the patient's heart. Therefore, how to obtain a three-dimensional image of the patient's heart is the key to early detection of coronary heart disease. [0003] The heart is the power source of the human circulatory system and one of the most important organs in the human body. Since the heart is located in the chest cavity, above...
