Abstract:: Abstract: The study presents a method for the personalized biomechanical modeling of the human head and validates the generated model. Based on the TUST 50th percentile head biomechanical model, the method utilizes head CT data of the target model, and employs three-dimensional point cloud registration and free-form deformation techniques to rapidly develop a personalized head finite element model with detailed brain tissue structures. By reconstructing classic cadaver tests, it is found that the personalized head biomechanical model created by the proposed method shows a good consistency with the results of cadaver tests in kinematic and biomechanical responses. Furthermore, no significant differences are observed when compared with the head biomechanical model developed using reverse engineering method, thus verifying the effectiveness of the developed model. Consequently, the proposed method can be used to quickly construct personalized head biomechanical models with detailed anatomical structures, providing a fundamental computational analysis tool for researches in injury biomechanics, clinical medicine, and forensic identification.
