A new method verifies radiation therapy delivery by measuring energy fluence pulse-by-pulse. This quality assurance technique accurately confirms treatment delivery, enabling real-time verification and dose reconstruction for conformal and conformal avoidance radiation therapy.

Area of Science:

  • Medical Physics
  • Radiation Oncology
  • Quality Assurance

Background:

  • Conformal and conformal avoidance radiation therapy utilize high dose gradients, necessitating stringent quality assurance for treatment delivery verification.
  • Accurate patient positioning and radiation delivery verification are critical for the success of these advanced radiation therapy techniques.

Purpose of the Study:

  • To develop and test a novel methodology for radiation delivery verification in tomotherapy.
  • To assess the accuracy and efficiency of a pulse-by-pulse energy fluence verification technique.

Main Methods:

  • A tomotherapy workbench was used to test a methodology for radiation delivery verification.
  • The technique measures exit detector signals to determine energy fluence and multileaf collimator (MLC) leaf states on a pulse-by-pulse basis.

  • Verification was performed on two phantom cases, one homogeneous and one with inhomogeneities, with varying beam configurations.

    • Main Results:

    • The developed process accurately verifies delivered energy fluence, with errors between planned and delivered values concentrated within +/-2.0% and none exceeding +/-3.5%.
    • The pulse-by-pulse verification allows for detailed comparison with planned delivery, enabling projection-by-projection analysis.
    • The technique demonstrated speed, suggesting potential for real-time radiation delivery verification.

    Conclusions:

    • The presented methodology provides accurate and efficient radiation delivery verification for conformal and conformal avoidance radiation therapy.
    • This technique can be extended for dose reconstruction, enhancing the quality assurance process.
    • The pulse-by-pulse verification approach offers a robust solution for ensuring treatment accuracy in advanced radiotherapy.
