Abstract

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.

摘要

X射线图像增强器（XRII）图像畸变校正是基于C型臂的手术导航系统中的一项关键技术。在本文中，我们提出了一种新的校正方法，该方法将移动最小二乘法（MLS）和多级B样条逼近法（MBA）相结合。实验表明，所提出的方法能够实现良好的图像校正效果，并且比现有的校正方法更精确。
