Modeling of three-dimensional CT imaging

YANG Ke-cheng,YE Yu-sheng,YU Xiao-e,LIN Yi-qun(School of Biomedical Engineering,Southern Medical University,Guangzhou,510515)  
Three-dimensional CT imaging(3D-CT)is broadly applied in such clinical applications as radiotherapy simulation.The displacement and distortion of 3D-CT for moving objects lie on its moving state and the scanning parameters.A mathematical model was set up based on theoretical analysis of CT scanning process.Thus the temporal resolution,displacement and distortion of theoretical 3D image can be deduced,which establish a strong foundation for future experiment study.
