    • Abstract
  • Projection simulation is the basis of CT simulation research.A fast simulation method for CT projection based on bisection was proposed in this paper,and then the simulation process was optimized.As long as a scanned object could be decomposed to individual convex items,arbitrary scanning trajectory could be used to simulate projection based on our method,and the projection accuracy could be infinitely close to theoretical projection accuracy.Numerical simulation results verify the effectiveness of our method.
