Summary
In order to promote 3D display techniques it is necessary to accelerate 3D acquisition devices. One solution is to use a 2D X-ray detector. In that case the acquisition procedure can be depicted by the divergent beam transform. For a circular trajectory near of the object, the slice by slice reconstruction is no more accurate. It is necessary to use a 3D reconstruction algorithm. This paper develops an original method based on an approximated evaluation of the 3D Radon Transform and on the use of its inversion formula.
