Objectives: Human digital twin (HDT) research and development that implements human body information in a virtual environment is actively progressing. Our research interest is the reconstruction of the musculoskeletal system. The Digital Korean Project established a database of Korean skeletons.
Methods: For the purpose of gathering morphological information about the human body, a database was created by performing whole body computer tomography (CT) scans on 100 donated Korean adult cadavers (50 males and 50 females) to construct individual skeletal models. These models were then averaged and standardized to create average skeletal models for Korean males and females. The material properties information, which represents the hardness level of the constructed models, has been compiled by differentiating cortical bone and trabecular bone.
Results: The results of this project were applied to creating various medical implants and utilized for producing educational content for medical personnel training. Digital representations of the human skeleton can be constructed at a higher level by including movement. Recently Reconstruction of the human shoulder musculoskeletal system and movements were performed using Digital Korean Database and patient's CT data, which served as a foundation for advancing it into HDT. And a visualization application was developed using the digital reconstruction of shoulder movements.
Conclusion: Further work is required to develop an algorithm to match real-world data with human digital twins. These studies will provide a framework for the development of HDT that include comprehensive modeling of whole body.
