A Novel Method Using Camera Calibration Technique for Complete Geometric Calibration of Cone-beam CT

摘要：

　　Cone-beam computed tomography (CBCT) is deployed in large numbers for small animal imaging.For accurate reconstruction,geometric parameters of CBCT must be known.In this paper,a novel method using camera calibration technique for CBCT geometric calibration is proposed.Geometric relationships of X-ray source,detector and rotation axis are obtained to calculate CBCT geometric parameters.Simulation results show that accuracy of this method is improved compared with previous methods.
