This study determined 10 MV x-ray phantom scatter correction factors (Sp) using three methods. The derived scatter-maximum ratios (SMRs) closely match Monte Carlo simulations, validating the approach.

Area of Science:

  • Medical Physics
  • Radiotherapy Physics

Background:

  • Accurate scatter correction is crucial for precise dose calculations in radiotherapy.
  • Phantom scatter correction factors (Sp) are essential for modeling radiation transport in heterogeneous media.

Purpose of the Study:

  • To determine 10 MV x-ray zero-area phantom scatter correction factors (Sp) using multiple methods.
  • To produce and parameterize scatter-maximum ratios (SMRs) for 10 MV x-rays.
  • To validate the derived Sp values against Monte Carlo simulations.

Main Methods:

  • Obtained three sets of Sp data using methods based on the Bjärngard-Petti extrapolation principle.
  • Assumed lateral charged particle equilibrium (CPE) for primary absorbed dose.
  • Produced and parameterized a set of SMRs using the most reliable Sp data.

Main Results:

  • Derived Sp values using three distinct methods, all assuming lateral CPE.
  • Developed a parameterized expression for 10 MV x-ray SMRs.
  • The parameterized Sp (0; 2.5) was 0.931, showing good agreement (0.4% difference) with a Rice-Chin Monte Carlo simulation value of 0.927.

Conclusions:

  • The Bjärngard-Petti extrapolation principle provides reliable Sp data for 10 MV x-rays.
  • The parameterized SMRs offer an accurate representation of scatter correction factors.
  • The results demonstrate good agreement between the proposed method and advanced Monte Carlo simulations for radiotherapy dose calculations.
