Virtual-Real Registration of Augmented Reality Technology Used in the Cerebral Surgery Lesion Localization
Shaofang Lu, Xiaoming Lin, Xue Han · 2015
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.
