Skeleton model construction method and device, computer equipment and storage medium

Abstract

The invention discloses a skeleton model construction method and device, computer equipment and a storage medium, and the method comprises the following steps: carrying out the preprocessing of a skeleton tissue, so as to determine the contour boundaries of a cortical bone and a cancellous bone; extracting contour boundaries of the cortical bone and the cancellous bone, carrying out three-dimensional curved surface modeling, and obtaining a preliminary model; and further processing the preliminary model to obtain a finite element model with continuously variable cortical bone thickness. According to the method and device, skeleton tissues are preprocessed, cortical bones and cancellous bones of skeletons are distinguished, contour boundaries of the cortical bones and the cancellous bones are determined, the contour boundaries of the cortical bones and the cancellous bones are extracted, and three-dimensional curved surface modeling is carried out, so that a constructed preliminary model is closer to a real skeleton structure, and skeleton characteristics are accurately reproduced in the medical field; and the preliminary model is further processed to obtain a finite element model which reflects the continuous variable cortical bone thickness in a real bone structure.

Description

technical field [0001] The present invention relates to the field of skeleton model simulation, and more particularly to a skeleton model construction method, device, computer equipment and storage medium. Background technique [0002] Bone is an organ with a unique structure of high-density connective tissue, which is mainly divided into cortical bone and cancellous bone in structure. Cortical and cancellous bone differ greatly in structure, material and mechanical properties. The outer layer of the bone is compact cortical bone and the inner layer is honeycomb-shaped cancellous bone, of which cancellous bone accounts for 20% of the bone mass but constitutes 80% of the bone surface. The bone density of cancellous bone is lower than that of cortical bone, but it is more elastic; the scaffolding structure of cancellous bone helps to maintain bone shape, resist pressure, and constitute most of the axial bone. In actual skeletal anatomy, the outer cortical bone and inner canc...

Problems solved by technology

However, in the previous 3D finite element model construction of bone tissue, the cortical bone and cancellous bone structure of the bone were not usually distinguished, but the entire bone structure was homogenized; or although the cortical bone and cancellous bone structure were distinguished, the Does not truly reflect the continuous variation in cortical bone thickness in the skeletal structure
