摘要:
本研究旨在增强现实(augmented reality,AR)导航系统在穿支皮瓣手术中的应用,从三维注册方法以及模拟医生在动、静不同状态下,探究这两种因素对注册精度的影响,开发了基于HoloLens的AR手术导航系统,包括两种三维注册方法:基于识别图的AR注册方法和交互式无标识的AR注册方法。为客观验证AR手术导航系统的注册精度,本研究对注册精度的测试方法进行了研究,使用Micron Tracker对虚实测试点的三维坐标进行测试与分析。基于识别图的注册方法,其总误差、静态注册误差、头部转动注册误差及走动注册误差分别为(3.98±0.19)、(3.78±1.57)、(4.23±1.27)、(3.92±1.32) mm;基于交互式无标识注册方法,其总误差、静态注册误差、头部转动注册误差及走动注册误差分别(6.56±0.80)、(5.60±0.53)、(6.52±1.14)、(7.57±1.09) mm。结果表明,基于识别图的注册方法精度更高,表现最佳。两种注册方法的静态注册误差均小于动态注册误差,说明转动头部及走动对注册精度有显著的影响。
Abstract:
To analyze the application of augmented reality (AR) navigation system in perforator flap surgery, we explored the influence of 3D registration method and simulated doctors in different dynamic and static states on registration accuracy,to develop AR surgical navigation system based on HoloLens.It included of two 3D registration methods: AR registration method based on recognition map and interactive unmarked registration method. In order to verify the registration accuracy of AR surgical navigation system objectively, we studied the test method of registration accuracy. The Micron Tracker was used to test and analyze 3D coordinates of virtual and real test points. The registration method based on the recognition map, the total error,static registration error,head rotation registration error and walking registration error were(3.98±0.19),(3.78±1.57),(4.23±1.27 ),(3.92±1.32)mm respectively; Based on the interactive unmarked registration method, the total error,static registration error,head rotation registration error and walking registration error were respectively(6.56±0.80),(5.60±0.53),(6.52±1.14),(7.57±1.09)mm. The results show that the registration method based on recognition map has higher precision and the best performance. The static registration error of the two registration methods is less than the dynamic registration error, indicating that the head rotation and walking have significant influence on the registration accuracy.
