Abstract
To perform cone beam reconstruction by using projection data correctly corresponding to X-ray beam having passed through each pixel in the reconstruction area, data Dis obtained which is plane projected to a plane based on projection data D. Then, plane projection data Dto the projection plane pp is projected to the reconstruction area in the direction of X-ray transmission to obtain back projection pixel data D. Thereafter, back projection pixel data Dwill be added for each corresponding pixel for all views to obtain back projection data D. The present invention provides reconstruction by device of projection data correctly corresponding to the X-ray beam having passed through the reconstruction area. Through the plane projection to a plane the operation will become simplified and faster.
