Abstract:
Objective To reduce the artifacts produced by cardiac or respiratory motion,through the application of exact reconstruction algorithm with triple-source CT in dynamic reconstruction.Methods Simulation studies on two dynamic phantoms were performed with exact reconstruction algorithms of both single-source and triple-source spiral CT.The performance of triple-source spiral CT in dynamic reconstruction was evaluated with comparing the reconstruction results from triple-source and single-source configurations.Results The triple-source configuration could effectively reduce the artifact in dynamic reconstruction.Conclusion The results of this paper confirm the validity of the exact reconstruction algorithm of multi-source CT,which has the potential to improve the image quality in cardiac imaging and small animal imaging.
