[Detector efficiency for non-helical trajectory of cone beam reconstruction].
Using the present cone beam reconstruction formula for general trajectory, we have investigated the issue of detector efficiency for non-helical trajectory. The results reveal that the two factors dominating the detector efficiency are detector geometry and filtering directions. The methods for to higher detector efficiency are proposed, and the reliability and feasibility are tested by simulation results.
