Background:

  • Clinical dose calculations often rely on scaling methods between different media.
  • These methods approximate dose distributions by mapping from a reference medium.
  • Existing techniques like linear density scaling have limitations in accuracy.

Purpose of the Study:

  • To develop a novel mapping algorithm for electron dose calculations.
  • To identify conditions under which particle transport can be simplified to a mapping form.
  • To improve the accuracy of dose calculations in various clinical scenarios.

Main Methods:

  • Developed a continuous scattering mapping based on medium scattering and stopping powers.
  • Identified five conditions for particle transport to conform to a mapping structure.

    • The new mapping algorithm approximately satisfies the identified conditions for electron transport.
    • Calculated dose distributions were compared with direct EGS4 calculations in second media.
    • The continuous scattering mapping demonstrated superior accuracy compared to linear density scaling and the MDAH algorithm.

    Conclusions:

    • The developed continuous scattering mapping offers a more accurate approach for electron dose calculations across different media.
    • This method is effective for both homogeneous media and inhomogeneous phantoms in various geometries.
    • The algorithm shows significant potential for enhancing precision in clinical radiation therapy dose planning.
