[Development of the first head finite element model based on Chinese visible human data]

Area of Science:

• Biomedical Engineering
• Computational Anatomy
• Finite Element Analysis

Context:

• The development of detailed anatomical models is crucial for understanding human head biomechanics.
• Previous models often lacked the anatomical precision required for specific research applications.
• The Chinese Visible Human (CVH) dataset provides high-resolution anatomical data.

Purpose:

• To construct a highly accurate finite element model of the Chinese head.
• To leverage the second CVH dataset for improved 3D reconstruction and meshing.
• To create a robust computational tool for head-related biomechanical studies.

Summary:

• A precise finite element model of the Chinese head was generated using the second CVH dataset through 3D image reconstruction and solid modeling.
• The model incorporates detailed anatomical structures including the skull, facial bones, brain, and cerebellum.
• It features 31,223 nodes and 19,911 solid elements, meeting engineering quality standards.

Impact:

• This model demonstrates enhanced accuracy, particularly in the cranial base regions, compared to existing CT/MRI-based models.
• It represents a significant advancement in the application of the CVH platform for creating sophisticated anatomical models.
• Facilitates more accurate simulations in areas like traumatic brain injury and surgical planning.
