Proton Therapy in Oncology

I am developing my knowledge of proton therapy and its computational applications in oncology.

Proton therapy uses charged particles to deliver radiation to tumours. Its characteristic depth-dose behaviour makes it possible to concentrate dose within the treatment target while reducing unnecessary exposure to surrounding healthy tissue.

My interests include proton interactions with matter, treatment simulation, dose calculation, medical imaging integration, dosimetry, treatment planning, and computational methods for radiation oncology.

  • Bragg peak and depth-dose behaviour
  • Energy loss and dose deposition
  • Treatment planning fundamentals
  • Absolute and relative dosimetry
  • Target volumes and organs at risk
  • Range and setup uncertainties
  • Radiation protection

Computational Applications

  • TOPAS Monte Carlo simulations
  • Geant4 fundamentals
  • CT-based patient geometries
  • DICOM radiotherapy data
  • Proton dose calculation
  • Dose distribution analysis
  • Deep learning for dose prediction
  • Scientific visualisation
