Abstract

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.
