A particle system approach to industrial tomographic reconstruction

This work introduces a novel tomographic reconstruction, using a very small number of projections, suitable for industrial applications. The particle system iterative reconstruction technique represents reconstructing material as a set of particles with certain physical features, subject to a group of forces, which can produce movement. The system constantly updates the net of particles by repositioning them in such a way as to approach the equilibrium. The elastic potential along a trajectory is a function of the difference between the attenuation coefficient in the current configuration and the corresponding input data. In this work, we present a simple analysis of the resulting reconstruction in a simulation with sinograms produced from some phantoms, including a comparison with some established iterative methods.
