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 triplesource 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 triplesource 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.
