Influence of registration markers' shape on the registration accuracy of 3D images
摘要
Abstract
Objective To investigate the influence of the different shape of the registration markers on the registration accuracy of 3D images.Methods Totally 4 kinds of markers with different shapes were used to register the samples' CBCT 3D images to their original 3D images respectively.The distance between the two kinds of 3D images was measured and the effect of different shapes of markers on the registration accuracy of 3D images was analyzed.Results The registration deviation was cubical marker (0.0938 ± 0.0062)mm,spherical marker (0.0854 ± 0.0056)mm,cylindrical marker (0.1032 ± 0.0061) m m,and truncated cone marker (0.0972 ± 0.0062) mm;statistical significance only existed between the spherical marker group and other groups (P ＜ 0.05).Conclusion All of the markers in this experiment can be used to achieve 3D image registration precisely.In comparison,the spherical marker has higher registration accuracy.关键词
