Studies on Reconstruction Algorithms for Material Imaging with MST

Abstract

In case of Muon Scattering Tomography (MST), one of the basic algorithms used for image reconstruction is the Point Of Closest Approach (POCA) algorithm. Here, a preliminary work is presented on simulation studies for the efficacy test of POCA algorithm performed by comparing it with a calculation done by GEANT4. The inelastic Coulomb scattering vertices for interactions of muons and atomic nuclei are determined from GEANT4 simulations. On the other hand, point of the POCA algorithm is calculated from the incoming and outgoing tracks of the muon. Distance between the point found using POCA algorithm and mean point of scattering heads is calculated for each event. Smallness of this distance attests the competence of the algorithm.
