Abstract

We demonstrate for the first time the feasibility of Coherent Scatter Computed Tomography (CSCT) with a fan geometry primary beam. CSCT allows superior tissue characterization and diagnosis by reconstructing the structure function rather than the attenuation properties as in regular CT. To study the feasibility of CSCT, Monte-Carlo based simulations of scatter distributions of technical phantoms were carried out. The projection data were used as input fro a novel algebraic reconstruction technique which takes account of the details of the measurement geometry. First results are discussed showing the potential of CSCT. The influence of achievable angular collimation quality is investigated and an outlook on future work is given.
