Objective:A novel method was proposed for human skeletal muscle 3D fast reconstruction based on MRI in this paper. Method:The typical motions were selected and measured by MRI, the skeletal muscle cross-sections images were acquired. The motion were designed for 4 phases, the interval is 30°. Based on the level-set theory and volume element algorithm, a novel skeletal muscle MRI registration and segmentation method was developed. The 3D models and simulations of human skeletal muscle were reconstruction during human motions. Results:The dynamical MRI data were acquired during human typical motions, The regulation mechanism of human skeletal muscle during human motion were modelled and simulated. Conclusion:A new image segmentation algorithm and three-dimension reconstruction algorithm was developed. The biomechanical behavior and coordiantion pattern will be illustrated, and the mechanism of the skeletal muscle force will be further revealed based on this method.
