Abstract:In many radiation imaging applications, such as X-ray computerized tomography or nuclear medicine, tomographic systems have been recently developped, which image an object from an angulary restricted number of projections. It is well known that in such a case, some Fourier components are missing {1}, and thus analytical reconstructions, such as Fourier synthesis can no longer be used. But, the algebraic methods allow to take advantage of "a priori" informations on the object, in order to recover the missing da… Show more
