Abstract: BACKGROUND: Nowadays, there are increasing reports on the digitization and visualization system of acupuncture points for adults in traditional Chinese medicine, and the digitization and visualization system of acupuncture points for children in traditional Chinese medicine and the simulation system of acupuncture manipulation for Mongolian medicine training have been reported. However, there are no reports on relevant systems for children in Mongolian medicine.
OBJECTIVE: To develop a simulation system of acupuncture points for children in Mongolian medicine, in the hope that it can be used for clinical teaching, manipulation practice and research on acupuncture safety.
METHODS: Based on the tomographic anatomical dataset of preschool boys, a three-dimensional (3D) digital virtual anatomical model of children with multiple internal organs and tissues was constructed by using PhotoShop.2021 and Digihuman Reconstruction System software. The relevant annotation information database of 27 acupoints such as Dinghui acupoint of Mongolian medicine was compiled by the Unity database language. The Mongolian gold needle and silver needle were selected to record the acupuncture point teaching video on the 3D printed head and neck resin model of children. In Unity3D software, children’s anatomical model, acupoint annotation information database and acupuncture operation video were integrated and coded, and a 3D digital children’s Mongolian acupuncture acupoint visualization system integrating simulation acupuncture training, clinical teaching and acupuncture safety research was successfully created.
RESULTS AND CONCLUSION: This study was based on real children’s specimens. In order to reduce the error of two-dimensional segmentation, the manual layer-by-layer segmentation section image method was used to ensure the accuracy of the 3D model to the greatest extent. The Digihuman Reconstruction System was used to extract and save the individual segmentation data while maximizing the accuracy of the 3D model. PhotoShop.2021 software was used to complete the 3D reconstruction of the outer skin of the head and neck of children and the internal bony structure, cervical spinal cord, blood vessels and nerves, muscles and ligaments. After 3D reconstruction, the basic morphology of each independent structure and the integrity of the overall contour were verified in MeshLab software and the final fine adjustment and anatomical position confirmation were conducted using 3-matic research 13.0 software. The real anatomical morphology of the head and neck of preschool children was successfully simulated and restored. Unity3D software was used to integrate the 3D model of children, acupuncture operation video and acupoint annotation database, and the 3D digital Mongolian acupuncture acupoint visualization system for children was successfully constructed. Based on the real continuous fault ultra-thin dataset of preschool boys in China, China’s first 3D digitization and visualization system of acupuncture points in the head and neck of children in Mongolian medicine was developed. Compared with the previous acupuncture soft works, this system is more suitable for the anatomical morphological development characteristics of Asian children, and has a high value of application in the fields of research on the safety of acupuncture in Mongolian medicine, clinical teaching and acupuncture simulation training.
