- Figure out monitor units and acquisition times for each field size
- Learn how to remotely control DSLR camera with software on laptop.
- Paper to be written and submitted to BJR or ... , after measurements are taken.

- Radiotherapy course 2nd term
Completed
2nd year
- 1st term
- G4 Separate Scintillation and Cerenkov photons in scintillator sheet simulation
- Whole beam produces Cerenkov photons in the plastic slabs+scintillator sheet while Scintillation is only produced in the scintillator sheet.
- A "scintillation only" image produces PDD, profile and Output factor within 2% of actual dose.
- Birmingham Meeting 9th Dec With Adam, Simon, Geoff, Hamid, Spyros
- Presented simulation results
- Methods to separate Cerenkov and scintillation, concluded with:
image plastic block (cerenkov) and then image scintillator sheet sandwiched by plastic slabs (scintillation + cerenkov) and then subtract - Plans for experiment in January with scintillator sheet sandwiched between plastic
- Talked about using the system for treatment plan verification by comparing a video to simulation.
- PhD transfer Report
- PhD transfer Viva - passed yay
- CDT presentation of 1st year work
- G4 Separate Scintillation and Cerenkov photons in scintillator sheet simulation
1st year
- Summer
- Summer School STFC Data Intensive, Artificial Intelligence and Machine Learning Summer School 2019
- G4 Simulate PDD, profile and Output factor from a scintillator sheet sandwiched between 2 platic slabs:
- PDD agrees within 2% but profile and Output factor(OF) doesn't.
- Cerenkov coming from plastic slabs distorts OF and profile.
- This is because as you increase the beam width, the amount of X-ray going into the plastic slab is proportional to (beam width)2
but the amount of X-rays going into the sheet is proportional to beam width.
- 3rd term
- Workshop Went to workshop - "Challenges and opportunities within practical small field dosimetry" - 9th may
- G4 Simulate image of an irradiated scintillator block and compared it's pdd with image from CCD camera.
- ~100,000 optical photons collected by lens given ~10,000,000 x-ray photons, which took 3 hours.
- G4 Speed improvements of scintillator block image:
- can use 4 lens' as there is 2 planes of symmetry => simulation captures 4x as much photons
- Use HEP batch farm to run jobs on 100 cores
- kill optical photons which would be internally reflected by all sides of block at there 1st step => simulation ~10x faster
- 2nd term
- Courses: Machine learning with big data, Inverse problems in imaging
- Group placement project: exploring the simulacrum cancer dataset from PHE (partnered with Valtech)
- presentation
- report
- G4 Import phase space file (cyberknife) beam to use as primary generator.
- G4 Simulate PDD, profile dose distributions in water and compare with measured.
- 1st term
- Courses: Standard model 1 & 2, Prob and stats, Research software (python)
- G4 Learning Geant4 with:
- ED-Geant4 - Lectures with exercises and solutions from an intro G4 workshop in 2018.
- Geant4 book - Reference for G4.
