| Abstract: | Based on the analysis for geometric distortion sources and their expressions of X-ray C-ann image, a template-based correction method is proposed and implemented. The schemes for evaluating the error distribution of C-ann image geometric distortion are designed and experimented. According to the results, variation characters of geometric distortion under different C-ann positions and orientations are discussed and the clinically available angle range of the correction matrix obtained under the specific pose is concluded. At last, the accuracy and effectiveness of this method is proved in the clinical surgery of distal locking of robot-assisted intramedullary locking. |
