Monte-Carlo methods in radiotherapy treatment planning

We are working on the clinical implementation and verification of the BEAMnrc Monte Carlo simulation system in combination with open-radART, our in-house developed record and verify system (R&V). It is possible to define all required beam parameters for a treatment plan which are adopted by the monte carlo simulation software within open-radART.

The developed software optimises phase space file calculations, depending on predefined configurations and beam parameters. A simulation of a patient treatment plan needs only one initial user interaction and can be used subsequently for research studies.

Furthermore, we perform monte carlo simulations for different research projects, such as:

  • Modeling of accelerator heads
  • Kernel-simulations for artifact deconvolution of new detectors
  • New X-ray imaging system simulations
  • Simulations for optimisation of DRR calculations
  • Neutron fluence and spectrum simulations in proton and carbon ion therapy
