Virtual-real Registration of Augmented Reality Technology Used in the Cerebral Surgery Lesion Localization

In the traditional cerebral surgery operation, the location of the lesion is difficult to calculate accurately. This paper designed a medical augmented reality system to locate the lesion via virtual-real registration technology. Firstly, a four-ball bracket was designed and fixed on the real skull. The virtual skull model with the virtual four-ball bracket was got by CT data reconstruct. The virtual lesion was added in the virtual skull model and the four-ball bracket was used for spatial position calibration of virtual model and real skull in the process of virtual-real registration. The whole virtual-real registration process was displayed on the computer in real-time. Finally, the application of virtual-real registration technology in the lesion localization of cerebral surgery was realized.
