Repositioning the Human Body Lower Extremity FE Model 2009-01-0922

This study aims to develop a methodology to generate anatomically correct postures of existing human body finite element models while maintaining their mesh quality. This repositioning is often done by running dynamic simulations. Such simulations, while taking a lot of time have the disadvantage of giving distorted elements as well as require a lot of expertise and have subjective interventions. Also, the anatomical correctness of the final position, and the kinematics followed during repositioning by dynamic simulations are uncertain. The developed method is based on computer graphics techniques and repositions a joint in just a few seconds. Repositioning of the lower extremity was also carried out using Finite Element (FE) simulations and analysed. The repositioning results from the two techniques were compared and it was found that the technique based on computer graphics gave satisfactory results.
