Abstract
Discrete Tomography is a modern research field dealing with the reconstruction of an image from its projections when that image is assumed to have only a small number of gray values. When this assumption is (approximately) valid, a high quality reconstruction can be computed from only a small number of projections. In this paper, discrete tomography is applied to reconstruct the trabecular bone system of a mouse from a small number of micro- CT projections. The set of gray values in the reconstruction is restricted to only three values (background, soft tissue, and bone). Our results show that by using discrete tomography, a much better reconstruction of the trabecular bone structure can be obtained than by thresholding a continuous reconstruction from the same number of projections.
