Abstract
Design of medical imaging systems based on the detection of small-angle x-ray scattering is a subject of renewed interest. The potential of coherent scatter-based techniques for tissue characterisation has been recently investigated both theoretically and experimentally by several authors [1–4]. Measured molecular form factor data are now available for some tissues and tissue-equivalent materials [5–8]. An adaptation of these data to the standard EGS4 code has been very recently performed as part of a Monte Carlo simulation study for mammographic applications [9]. The PEGS4NB mortran file, which is included in the LSCAT package [10] was modified in order to read new data (form factors and cross sections) that take into account the effects of molecular interference in coherent scattering. The interference effect in coherent scattering for seven materials of biological interest is now incorporated in the new version of LSCAT [11].
