Development of discrete tomography for transmission electron microscopy: 3D imaging of interfaces in ceramic and semiconducting multilayers.

The main goal of this project is to develop discrete tomography for electron microscopy. As a starting point for the development of new reconstruction algorithms, the DART (Discrete Algebraic Reconstruction Technique) algorithm will be used. DART is an iterative algebraic reconstruction algorithm that is currently being developed at VISION LAB. It alternates between steps of the SIRT algorithm from continuous tomography and certian descretization steps. Within the SIRT iterations, subsets of the pixels are fixed at one of the constant grey levels, creating a new system of equations with fewer unknown than the original system.
