3D Forward and Back-Projection for X-Ray CT Using Separable Footprints
The greatest impediment to practical adoption of iterative methods for X-ray CT is the computation burden of cone-beam forward and back-projectors. Moreover, forward and back-proje...

Hardware acceleration of iterative image reconstruction for X-ray computed tomography
X-ray computed tomography (CT) images could be improved using iterative image reconstruction if the 3D conebeam forward- and back-projection computations can be accelerated signif...
