This study modified the MEVAPLAN system for fast neutron therapy, enabling separate calculation of neutron and photon components. This improves treatment planning accuracy by incorporating organ-specific kerma corrections and transmission calculations using CT data.

Area of Science:

  • Medical Physics
  • Radiation Oncology
  • Radiotherapy Physics

Background:

  • Accurate treatment planning for fast neutron therapy requires separate calculation of neutron and photon radiation components.
  • Existing systems like MEVAPLAN (Siemens) needed modifications to handle these distinct calculations.

Purpose of the Study:

  • To adapt the MEVAPLAN system for precise fast neutron therapy planning.
  • To implement methods for calculating neutron and photon dose components separately.
  • To enhance accuracy through organ-specific corrections and transmission calculations.

Main Methods:

  • Modified the MEVAPLAN system's database and source code.
  • Implemented kerma-corrections for organs with varying atomic compositions.
  • Utilized linear attenuation coefficients and CT data for neutron transmission calculations.
