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 D1is obtained which is plane projected to a plane based on projection data D0. Then, plane projection data D1to the projection plane pp is projected to the reconstruction area in the direction of X-ray transmission to obtain back projection pixel data D2. Thereafter, back projection pixel data D2will be added for each corresponding pixel for all views to obtain back projection data D3. 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.
