In discrete tomography, a scanned object is assumed to consist of only a few different materials. This prior knowledge can be effectively exploited by a specialized discrete reconstruction algorithm such as the Discrete Algebraic Reconstruction Technique (DART), which is capable of providing more accurate reconstructions from limited data compared to(More)
In X-ray tomography, a number of radiographs (projections) are recorded from which a tomogram is then reconstructed. Conventionally, these projections are acquired equiangularly, which intrinsically assumes that the information added by each projection does not depend on the angular spacing. However, especially in case when only a limited number of(More)

CT reconstructions of a slice of cheese using conventional and inline scanning geometries. Due to the angular imaging constraints, the low number of available projections and the existence of truncated data, the(More)
