Human bone model establishing method based on bone imaging

Abstract

The invention relates to a human bone model establishing method based on bone imaging. The method comprises the following steps: S1, acquiring bone imaging data, and reconstructing a bone imaging dataset; S2, adopting a human bone tissue recognition algorithm to recognize bone tissue in bone imaging in order to obtain a bone tissue data set; S3, performing down-sampling on the bone tissue data set by adopting a human bone tissue centralization algorithm to obtain a human bone model point metadata set; and S4, establishing a human bone model through a meshless method by utilizing the human bone model point metadata set. Compared with the prior art, the method has the advantages of low cost, high precision and the like.

Description

technical field [0001] The invention relates to the field of medical image processing, in particular to a method for establishing a human bone model based on bone imaging. Background technique [0002] Human skeleton extraction technology is an important technology in the field of human-computer interaction. It has a wide range of application prospects in 3D animation production, online games, medical science, gesture capture and natural human-computer interaction environments. Due to the complexity and irregular shape of the human body model, as well as the diversity of human body posture changes, the automatic extraction process of bones is difficult, so the research on bone extraction for analysis has also received extensive attention. [0003] In the field of medical science, the establishment of a fine human bone model is an important prerequisite for the repair of osteoporosis with internal fixation implants. However, due to the intricate microstructure of the cancello...

[0003] In the field of medical science, the establishment of a fine human bone model is an important prerequisite for the repair of osteoporosis with internal fixation implants. However, due to the intricate microstructure of the cancellous bone in the human bone structure, the material properties of human bone have unique characteristics at the macro level. Strong randomness, for cancellous bone, it is more difficult to establish its human bone model

[0004] The finite element method in the computational mechanics method is widely used in the analysis of biological systems, and solves a large number of theoretical and application problems of biological systems. The finite element method has also become a general tool for biomechanical research. In the case of osteoporotic bone and internal fixation, it will lead to many difficult problems such as high mesh division cost and mesh distortion. At the same time, the established finite element model is also different from the real bone tissue structure in terms of mesoscopic continuity. access, high cost and low precision
