Imaging Algorithms for Cosmic Ray Muon Radiography Detection of Nuclear Materials

Cosmic ray muon radiography which has good penetration ability and is sensitive to high-Z materials, is an effective method to detect shielded nuclear materials. This paper summarizes methods developed to process muon radiography in Tsinghua University. The methods include detector data correction, recon-struction algorithms (maximum likelihood scattering, MLS, and the maximum likelihood scattering and displacement, MLSD) acceleration, and the modification of the normalized mean absolute distance measure (N...
