Abstract
A process for reconstructing three-dimensional images of an object with the aid of measurements performed by bidimensional arrays of sensors on a succession of incidences around the object. There are at least two circular coaxial paths (2,2') on which the arrays (4,4') are displaced. Thus, it is possible either to accelerate the taking of images, or increase the volume of the measurements, or accelerate the calculation of the reconstructed image, through the use of a single reference frame in whose coordinates the sums of the measurements on each sensor are characterized. The process has particular application to medical imaging or to the non-destructive inspection of parts in emission or radiation attenuation tomography.
