Area of Science:

  • Medical Physics
  • Radiation Oncology
  • Computational Modeling

Context:

  • Accurate simulation of linear accelerator (LINAC) heads is crucial for precise radiation therapy planning.
  • The BEAM Monte Carlo code is a standard tool for simulating radiation beams, but requires specific modules for advanced components like multileaf collimators (MLCs) and backup jaws.
  • Existing LINAC head models often use simplified geometries for collimating devices.

Purpose:

  • To develop and validate a Monte Carlo model for simulating the accelerator heads of two identical linear accelerators equipped with multileaf collimators (MLCs) and backup jaws featuring curved leaf-ends.
  • To assess the accuracy of the simulation by comparing calculated depth dose curves with measured data.
  • To investigate the dosimetric impact of curved leaf-ends in MLCs and backup jaws.

Summary:

  • A detailed Monte Carlo model of linear accelerator heads was created using the BEAM code, incorporating a novel module for backup jaws and the standard MLCQ module for MLCs with curved leaf-ends.
  • The simulation accurately reproduced measured depth dose curves in water, with discrepancies less than 2%.
  • The study found that the use of curved leaf-ends in both MLCs and backup jaws results in a higher shoulder in the y-profile compared to straight-ended designs.

Impact:

  • Provides a validated computational tool for accurate simulation of complex linear accelerator head geometries.
  • Offers insights into the beam shaping capabilities of modern MLCs and jaws, aiding in treatment planning optimization.
  • Contributes to the understanding of dose distribution characteristics in radiation therapy, potentially improving treatment efficacy and reducing off-target dose.
