Version 1.17 release notes

  1. Added projectors for a new geometry: cone-parallel. Cone-parallel coordinates are the standard for medical CT and are obtained by rebinning cone-beam data, so that each fan-beam is rebinned to parallel-beam. Note that the rays still diverge in the z-dimension and thus the name: cone-parallel. Cone-parallel is now fully supporting in LEAP, e.g., forward and back projection, FBP, helical, analytic ray tracing, iterative reconstruction, etc.
  2. Added rebin_parallel which rebins fan-beam to parallel-beam and cone-beam to cone-parallel.
  3. Fixed helical FBP scaling issue for curved detectors.
  4. Added set_FBPlowpass function which enables arbitrary smoothing of the ramp filter.
  5. Fixed bugs in preprocessing demo script.
  6. Added low signal correction preprocessing algorithm.
  7. Fixed bug related to forward projecting "small" voxels in parallel-beam coordinates.
