Angiocarpy image reconstruction method and system based on implicit deformable model

Abstract

The present invention provides an angiocarpy image reconstruction method and system based on an implicit deformable model. The method comprises the steps of: obtaining a human body heart three-dimensional image, and employing the parameters of the human body heart three-dimensional image to construct a nested function partial differential equation; employing a combination mode of a fast marching method and a collision forward method to initialize angiocarpy aorta images and coronary artery images, perform swelling, smoothing and convection processing, solve the nested function partial differential equation and obtain a reconstructed angiocarpy three-dimensional image; and employing marching cubes to perform processing of the reconstructed angiocarpy three-dimensional image to obtain an angiocarpy three-dimensional model. The method and the system solve the problem that the calculation stability is poor in a current angiocarpy image reconstruction method, achieve rapidly and accuratelysegment required areas on the premise of ensuring the calculation result stability, are simple to operate and facilitate later calculation of the hydromechanics analysis.
