Electron tomography is a powerful tool for investigating the three-dimensional structure of nanomaterials. The field of discrete tomography focuses on the reconstruction of samples that consist of only a few different materials. Ideally, a reconstruction of such a sample should contain only one grey level for each of the materials in the sample. By using this property in the reconstruction algorithm, the required number of projection images can be reduced substantially and the quality of the reconstruction can be improved. A discrete reconstruction typically contains fewer artifacts and does not have to be segmented, as it already contains one grey level for each material.

In this talk, the basic principles of discrete tomography will be introduced, followed by an overview of recent results on real-world microscopy data.
