摘要 影像增强器(XRII)图像失真校正是基于C型臂手术导航系统中的一项关键技术。本文提出一种新型校正方法,将移动最小二乘(MLS)法与层次B样条逼近(MBA)法进行有机集成。经实验验证,该方法在精度和对单元变形敏感度方面优于现有方法,图像校正效果好。 XRII image distortion correction is a key technique in a C-arm-based surgical navigation system. In this paper,we present a new correction method,which integrates the method of moving least squares（MLS） and the method of multilevel B-spline approximation（MBA）. Experiments show that the proposed method leads to good outcome of image correction and it is more accurate than the exsiting correction methods.
