Abstract To address the problems of lacking image guidance, prone to forgetting, and poor training results during simulated lateral ventricle puncture experienced by medical students, this study proposed an augmented reality (AR) glasses-based lateral ventricle puncture assistance system. Based on the CT and MRI data of a patient with mild lateral ventricle enlargement, the medical modeling software Mimics was used to threshold segment the gray characteristics of various tissue structures in the skull and brain, and a 3D virtual model was constructed. Next, AR construction was performed using Vuforia SDK and Unity 3D, and a method of combining the main recognition image with the opening image was proposed to obtain an average registration error of the system of 1.333 mm. At last, the system was imported into AR glasses and debugged. Twenty clinical medical students were invited to participate and were divided into two groups: one wearing AR glasses and the other not. They performed simulated lateral ventricle frontal horn puncture operations and scored the simulated surgery using a questionnaire. The test results showed that compared with the group not wearing AR glasses, the group wearing them used an average of 4.71 minutes less time during the operation, and the success rate of puncture increased by 30%. Furthermore, the group wearing AR glasses gave significantly better feedback on the questionnaire evaluation than the control group. In conclusion, the AR glasses-based lateral ventricle puncture assistance system built in this study can significantly improve the training effect of the surgery and provide a new idea for improving the quality of lateral ventricle puncture surgery training.
