Query: Muon Tracing and Image Reconstruction Algorithms for Cosmic Ray Muon
  Computed Tomography   Cosmic ray muon computed tomography ({\mu}CT) is a new imaging modality with
unique characteristics that could be particularly important for diverse
applications including nuclear nonproliferation, spent nuclear fuel monitoring,
cargo scanning, and volcano imaging. The strong scattering dependence of muons
on atomic number Z in combination with high penetration range could offer a
significant advantage over existing techniques when dense, shielded containers
must be imaged. However, {\mu}CT reconstruction using conventional filtered
back-projection is limited due to the overly simple assumptions that do not
take into account the effects of multiple Coulomb scattering prompting the need
for more sophisticated approaches to be developed. In this paper, we argue that
the use of improved muon tracing and scattering angle projection algorithms as
well as use of an algebraic reconstruction technique should produce muon
tomographic images with improved quality or require fewer muons to produce the
same image quality compared to the case where conventional methods are used. We
report on the development and assessment of three novel muon tracing methods
and two new scattering angle projection methods for {\mu}CT. Simulated dry
storage casks with single and partial missing fuel assemblies were used as
numerical examples to assess and compare the proposed methods. The simulated
images showed an expected improvement in image quality when compared with more
conventional techniques, even without muon momentum information, which should
lead to improved detection capability, even for partial defects.
