AI Article Synopsis
- - Source strength measurements are essential for brachytherapy, typically done in hospitals using specialized equipment called well-type chambers, but quality control can be challenging due to limited resources.
- - A study in Serbian hospitals focused on the measurement equipment's status and organized testing with a hospital Ir source, revealing that all hospitals achieved the necessary accuracy in measuring source strength, while emphasizing the need for better quality assurance practices.
- - The study established a framework for evaluating the performance of brachytherapy centers, including creating an uncertainty budget, which can be adapted for calibration procedures in various hospitals.
Article Abstract
Source strength measurements are of critical importance for brachytherapy and are often performed in hospitals using well-type chambers. Quality assurance and quality control procedures should be implemented, but that may prove difficult in some hospitals due to the lack of equipment or metrological support. A study was conducted to investigate the status of the measurement equipment in Serbian hospitals and to organize an intercomparison campaign using a hospital Ir source. All the hospitals were able to measure the source strength with the required accuracy, but the quality assurance can be improved. Two hospitals performed stability checks, which were evaluated. Uncertainty budget was created during the exercise and is presented in this paper. The described methodology can be used to quickly assess the performance of brachytherapy centers, and can be easily adapted to calibration procedure.
