Abstract
A patient (7) is irradiated by an X-ray source (1) in a computed tomography apparatus. The radiation is subsequently detected by the detector cells (5) of a position-sensitive X-ray detection system (4) and the intensities detected are applied to a computing device (16). Absorption as well as elastic and inelastic scattering of X-rays occur within the patient (7). The data acquired is corrected for elastic (coherent) scatter by deriving a deconvolution function from the elastic scatter function, which deconvolution function is applied to the data. The elastic scatter function is determined, for example by a computer simulation.
