[Development of the first head finite element model based on Chinese visible human data].
摘要
The second Chinese visible human (CVH) data has been used to build a more precise finite element model of Chinese head via 3-D image reconstruction, solid model reconstruction, finite element meshing, and assembling of finite element model. This second case of finite element model of Chinese head contains skull, facial bones, inferior maxilla, cerebral falx, brain, cerebellum brainstem, and so on. All the mesh elements, according to their main quality check results in line with the engineering requirements, were identified as solid elements, and the numbers of nodes and elements were determined to be 31 223 and 19 911 respectively. The model is coincident with the anatomy of human head; and its accuracy in some region, especially in fundus cranii and fundus cranii, is more excellent than that of the other models based on CT/MRL The development of the first head finite element model based on CVH data has brought on a remarkable progress in the application of CVH platform.
