Tomopy

• https://tomopy.readthedocs.io/en/latest/ipynb/tomopy.html

• gridrec reconstruction algorithm working

  • assumes parallel beam (not cone-beam)
  • ~10 minutes for reconstruction of 750 projections of 1.5k x 1.9k pixels
  • jupyter notebook works for decimated data (x1/2, x1/4) but stalls on the full dataset, regular python is recommended for large datasets

• visualization using ipyvolume in jupyter notebook

To do:

• cone-beam reconstruction

  • ASTRA toolbox in tomopy
  • or DIY
    • cone to para: https://www.medphysics.wisc.edu/research/ct/publications/documents/Cone-to-Parallel.pdf
    • FDK is commonly used for 3D reconstruction which rebins the cone-beam data as a tilted fan projection
      • one step further would be to rebin from cone --> tilted fans --> parallel

• see if the reconstruction of the full data set is more reliable on a heftier workstation

  • C14/Carbon?
