Abstract:

BACKGROUND: The three-dimensional reconstructed model by medical images data is mainly applied to clinical analysis, while the reverse reconstructed model by laser-scanning is usually used in biomechanical analysis. The accuracy of biomechanical model establishment directly affects the analysis results.
OBJECTIVE: To analyze the reconstruction methods and significance of medical organ model by medical images data and three-dimensional laser-scanning.
METHODS: ①The three-dimensional reconstruction was performed by medical reconstruction software based on human CT scanned images. ②Point cloud data of medical models analyzed by three-dimensional laser scanner were used to reverse reconstructing medical organ model with reverse treatment software.
RESULTS AND CONCLUSION: Both the two methods can build geometric model and finite element model accorded with human anatomy structure for biomechanical simulation calculation. The three-dimensional model reconstructed by CT/MRI images truly reproduced the surface characteristics and internal structure of cases being scanned, which could be used as a reliable model in clinical diagnosis, surgical planning, shaping, prosthetic design, and anatomy teaching. The reverse reconstructed model by point cloud data analyzes with laser-scanning could show the case surfaces. It could be used in computer simulation analysis of human organs blunt impact by transportation and military.
