Implementation of gamma-ray transmission tomography in a multi-modality tomographic scanner for nuclear materials in shielded radioactive waste drums - simulation data
Description
Geant4 simulation data in CERN Root-format. The data result from a simulation study on step-and-shoot computed tomography (CT) using a cylindrical NaI(Tl)-detector and a point Co-60 source. The data is used to reconstruct tomographic image slices of a mock-up drum geometry built in Geant4. The source was simulated as a cone beam of 1/27th of a sphere with a million events per energy and measurement step in the full scan. The scan was simulated with increments of 3-degree rotation and 1 cm translational steps to complete full coverage of the width of the drum (in total 720 mm) per rotation in a 180-degree arc. The images can be reconstructed through an algorithm such as filtered back-projection.

Steps to reproduce
The data was generated through a simulation program written with the Geant4-toolkit. A macro was used to execute the program with a new geometry corresponding to the motion steps described in the description of the data. Part of the data was generated using computing resources at the PDC Center for High Performance Computing, KTH Royal Institute of Technology, Sweden.
