Abstract

The invention provides a heart model building method, which comprises the following steps: providing a heart tomographic image, obtaining the point information of the heart tomographic image, and establishing a heart model corresponding to the heart tomographic image on the basis of the point information. The invention also provides a heart model registration method and a heart multi-plane reconstruction method. A heart model base is established to carry out registration on one heart model and a point set obtained by the calculation of an input heart image; then, according to a transformation relationship obtained by the registration, a key point position corresponding to the heart in the input image is obtained through mapping the key point position of the heart model; and according to the obtained key point position, calculating the directions of a long axis and a short axis. The new frame and method provided by the invention can quickly and effectively realize the multi-plane automatic reconstruction of the heart tomographic image.

Description

technical field [0001] The invention relates to the field of medical image processing, in particular to a method for establishing, registering and multi-plane reconstruction of a heart model. Background technique [0002] The position of the heart in the human thoracic cavity varies greatly from individual to individual, and the standard orthogonal axis planes of the body, such as the transverse, coronal, and sagittal planes, cannot be used for tomographic display. In order to have a unified anatomical description of the heart, such as reference 1: Manuel D. Cerqueira, Neil J. Weissman, et al. Standardized myocardial segmentation and nomenclature for tomographic imaging of the heart [J]. Journal of American Heart Association, 2002 , 105:539-542., the American Heart Association (American Heart Association, AHA) in 2002 defined the standard of view and direction of cardiac tomographic imaging. The short axis, vertical long axis and horizontal long axis are used to describe th...
