Paper Abstract

In X-ray medical imaging,the promotion of 3D display techniques imposed to improve the spatial and temporal resolution of 3D acquisition-reconstruction devices. One solution is to use a 2D X-ray detector. For one source position,the attenuation measurement of the diverging X-ray beams provides a radiography. The source trajectory defines a set of acquisitions. In terms of illposed problems, we state that a circular trajectory centred on the area to reconstruct can be a good one, provided the source remains far enough from the object. We propose a direct reconstruction algorithm based on an approximated evaluation of the 3D Radon Transform and on the use of its inversion formula. We present the numerical foundations of such a transform method.
