    This study compared radiation therapy doses across five Ontario centers using ionometric measurements. Results showed excellent agreement between clinical and reference doses, indicating accurate radiotherapy calibration.

    Area of Science:

    • Medical Physics
    • Radiotherapy
    • Radiation Oncology

    Background:

    • Accurate radiation dose calibration is crucial for effective cancer treatment.
    • Ionometric dose intercomparisons ensure consistency and reliability in radiotherapy delivery.
    • Variations in dose calibration can impact patient outcomes.

    Purpose of the Study:

    • To conduct an ionometric dose intercomparison for eight accelerators across five radiotherapy centers in Ontario.
    • To evaluate the accuracy of clinical dose calibration procedures against a reference standard.
    • To identify areas for improvement in radiotherapy dose calibration.

    Main Methods:

    • An ionometric dose intercomparison was performed on eight medical accelerators (6-32 MeV photon energies).
    • Measurements were conducted at five radiotherapy centers in Ontario.

  • Dose ratios were calculated comparing clinically employed units to committee-representative measurements.

    • Main Results:

    • The mean ratio of clinically employed dose to reference dose was 0.994 (range 7.3%, CV 2.5%).
    • The mean ratio of institutional physicist dose to reference dose was 1.000 (range 6.9%, CV 2.3%).
    • These findings indicate high consistency in dose calibration across participating centers.

    Conclusions:

    • The ionometric dose intercomparison demonstrated a high level of agreement in radiotherapy dose calibration.
    • Clinical and institutional physicist measurements closely matched the reference standard.
    • Eight recommendations for improving dose calibration procedures were proposed.
