Background: Auditing the treatment planning system (TPS) software for a radiotherapy
unit is of paramount importance in any radiation therapy department. A Plexiglas
phantom was proposed to measure the ionization of ۶۰Co high dose rate (HDR) source
and compare dose points in the planning system for auditing and verifying TPS.
Methods: Auditing was performed using a Plexiglas phantom in an end‑to‑end test, and relative
dose points were detected by a farmer‑type ionization chamber and compared with the relative
dose of similar points in TPS. The audit results were determined as pass optimal level (<۳.۳%),
pass action level (between ۳.۳% and ۵%), and out of tolerance (>۵%). Results: The comparison
of the collected data revealed that ۸۰% of the measured values were ≤۵% in the pass level,
and ۲۰% of the points were out of tolerance (between ۵% and ۶.۹۹%). Conclusion: This study
documented the appropriateness of the dosimetry audit test and this phantom design for the HDR
brachytherapy TPS.
