To Do


  • Nada

Higher priority

  • Work on progress report
  • Write code for benchmarking metrics analysis: CDF, noise and relative error
    • Design more appropriate phantom to evaluate MTF (cf. Plautz et al., 2016 and Mori and Machida, 2009)
  • Get in touch with R Schulte to get access to DROP and TVS-DROP algorithms (Update 18/02/2019: Ask Robert Johnson (rjohnson@ucsc.edu) for access to GitHub repo.)
  • Run preliminary simulations to test the metrics

Lower priority

  • Do reconstruction of simulation with >1 billion protons
  • Convert ITK images to DICOM
  • Assign ID to each proton to simplify matching
    • Concatenating run ID and event ID to a long string does not work as the string is truncated for some reason.
    • Alternative: Use a short hash? -> Need a hash function
  • Write script to move the required number of projection files into the current directory
  • Edit script 'backproject' to take an argument for the number of projections used


  • (01/02/2019) Implement phantoms to be used to determine MTF and CDF in Geant4: one uniform phantom with a single central non-uniform pixel and another truly uniform phantom
  • (14/02/2019) Write code for benchmarking metrics analysis: MTF
