Three-dimensional modeling method

Abstract

The invention discloses a three-dimensional modeling method. The method comprises the following steps: generating a topological surface morphology of medicinal three-dimensional marking data through a convex hull algorithm; initially generating a deformable sealed cambered surface which envelops all the acquired three-dimensional marking data points; iteratively approaching the deformable sealed cambered surface to the topological surface morphology by using a level set reconstruction method; and partially adjusting the deformable sealed cambered surface near each medicinal three-dimensional marking data, so that part of the deformable sealed cambered surface can be superposed with each three-dimensional marking data, thereby establishing a sealed smooth superpose model of which the accuracy approaches to the topological surface morphology of the medicinal three-dimensional marking data. By acquiring the medicinal three-dimensional marking data with medicinal ducts in the cardiac chamber, the medicinal three-dimensional mark data is performed three-dimensional surface reconstruction ao as to establish a three-dimensional surface model of which the accuracy approaches to the surface morphology of the endomembrane in the cardiac chamber; and the three-dimensional surface model can be used for supervising and assisting doctors to do researches of cardiac electrophysiology or arrhythmia.

Description

technical field The invention relates to a three-dimensional modeling method, in particular to a three-dimensional modeling method based on discretized medical three-dimensional mapping data based on minimum energy constraints. Background technique In the field of medicine, especially in the research and treatment of cardiac electrophysiology, it is necessary to analyze, study and refer to the three-dimensional surface morphology of the endocardium, as well as the intracardiac electrophysiological information attached to the surface morphology, in order to analyze the heart. Electrophysiological abnormalities and various arrhythmias. The three-dimensional surface model of the endocardium can intuitively and concisely describe the three-dimensional surface morphology of the endocardium and the intracardiac electrophysiological information attached to the three-dimensional surface morphology. There are many kinds of medical 3D modeling methods, which are mainly divided into ...
