✦ Synopsis

The transfer functions of the analyser-based imaging system are expressed and discussed in terms of the analyser point-spread function and of an offset function which takes into account the partial coherence characteristics of the X-ray beam, particularly its wavelength spread. A description of the imaging process in terms of ambiguity functions is presented and is used to discuss the validity conditions of the transfer functions.

A hybrid simulation approach is proposed to compute the contribution of scattered radiation in X-or c-ray imaging. This approach takes advantage of the complementarity between the deterministic and probabilistic simulation methods. The proposed hybrid method consists of two stages. Firstly, a set of
