Abstract

Large uncertainties in output factor (OF) small fields dosimetry motivated multicentric studies. The focus of the study was the determination of the OFs, for different linacs and radiosurgery units, using new-generation detectors. Intercomparison studies between radiotherapy centers improved quality dosimetry practices. Results confirmed the effectiveness of the studies to uncover large systematic inaccuracies in small field dosimetry.

摘要

输出因子（OF）在小射野剂量学中存在较大不确定性，这促使了多中心研究的开展。该研究的重点是使用新一代探测器，确定不同直线加速器和放射外科设备的输出因子。放疗中心之间的比对研究改进了剂量学质量控制措施。结果证实了这些研究在揭示小射野剂量学中存在的重大系统误差方面的有效性。
