Abstract:

BACKGROUND: Scholars in home and abroad have been used different methods for three-dimensional (3D) modeling of the human knee joint, according to their different focuses, the ultimate effect and methods were different.
OBJECTIVE: To make registration and fusion of reconstructed knee joint according to the characteristics from different modality images, which provides a convenient method for further biomechanics research.
METHODS: Different segmentation algorithms were implemented to different knee joint tissues according to the characteristics of image from CT and MR modalities using Mimics V 10.0. 3D reconstructions of different segmented images were performed, and the results were registered and fused.
RESULTS AND CONCLUSION: Based on reverse engineering principle, the bony structures such as femur, tibia, fibula, patella were reconstructed from CT serial sections, and meniscus, patellar ligament, medial collateral ligament, anterior cruciate ligament, posterior cruciate ligament were reconstructed from MR serial images. The reconstructed structures were successfully fused, and could be observed at any angle or observed individually, and could be measured. It is indicated that 3D models of knee joint based on image fusion from different modality images, which provides basis for research on computer-aided knee joint injury rehabilitation.
