Query: Neutron penumbral imaging simulation and reconstruction for Inertial
  Confinement Fusion Experiments   Neutron penumbral imaging technique has been successfully used as the
diagnosis method in Inertial Confined Fusion. To help the design of the imaging
systems in the future in CHINA. We construct the Monte carlo imaging system by
Geant4. Use the point spread function from the simulation and decode algorithm
(Lucy-Rechardson algorithm) we got the recovery image.
