Advanced reconstruction algorithms for electron tomography: From comparison to combination

In this work, the simultaneous iterative reconstruction technique (SIRT), the total variation minimization (TVM) reconstruction technique and the discrete algebraic reconstruction technique (DART) for electron tomography are compared and the advantages and disadvantages are discussed. Furthermore, we describe how the result of a three dimensional (3D) reconstruction based on TVM can provide objective information that is needed as the input for a DART reconstruction. This approach results in a tomographic reconstruction of which the segmentation is carried out in an objective manner.

► A comparative study between different reconstruction algorithms for tomography is performed.
► Reconstruction algorithms that uses prior knowledge about the specimen have a superior result.
► One reconstruction algorithm can provide the prior knowledge for a second algorithm.
