ELogs/JeremyOcampo

Electronic Log for Jeremy Ocampo.

To do

• G4 Simulate an image from a 1mm thick scintillator in a non-scintillating plastic slab
  • compare to image from thick scintillator block
  • this is to test the idea that we are seeing errors due to focal depth or light coming from different depths
• G4 Get profiles at different depths and compare to data
• G4 Get output factor curves and compare to data
• G4 Make code neater, add more macros
• Report Finish first draft of start of report.
• Group placement make poster of group placement project
• Camera Familiarize oneself with DSLR camera and software
• Reading

Completed

• Workshop Went to workshop - "Challenges and opportunities within practical small field dosimetry" - 9th may
• G4 Simulate image from a 10cmx10cmx20cm scintillator and compared it's pdd with image from dslr camera.
  • ~100,000 optical photons collected by lens given ~10,000,000 x-ray photons, which took 3 hours.
  • reduced computing time using multithreaded mode, and also using the symmetry of the system by adding more lenses to collect more light
• G4 Import phase space file (cyberknife) beam to use as primary generator.
• Group placement exploring the simulacrum cancer data from PHE - 12th april
• 2nd term courses Machine learning with Big data, Inverse problems in imaging
• G4 Learning Geant4 with:
  • ED-Geant4 - Lectures with exercises and solutions from an intro G4 workshop in 2018.
  • Geant4 book - Reference for G4.
