Abstract
As is well-known, most of the CT-reconstruction techniques that are currently used, are implicitely based on the (rather idealized) parallel-beam projection model. Possible discrepancies from the model (dispersion and/or scattering of the rays, imperfect parallelism of the projecting beam, etc.) are usually classified as disturbances. Here, we present a first result, concerning the error induced by a projecting beam, which pre sents a small divergency.
