Reporting on the first implementation of a proton dedicated commercial device (IBA Sphinx/Lynx) for daily Quality Assurance (QA) of scanned proton and carbon ion beams.
Daily QA trendlines over more than 3 years for protons and more than 2 years for carbon ions have been acquired. Key daily QA parameters were reviewed, namely the spot size and position, beam range, Bragg peak width, coincidence (between beam and imaging system isocenters), homogeneity and dose.
The performance of the QA equipment for protons and carbon ions was evaluated. Daily QA trendlines allowed us to detect machine performance drifts and changes. The definition of tolerances and action levels is provided and compared with levels used in the literature.
The device has been successfully implemented for routine daily QA activities in a dual particle therapy facility for more than 2 years. It improved the efficiency of daily QA and provides a comprehensive QA process.
报告质子专用商业设备（IBA 狮身人面像/ Lynx）首次用于扫描质子和碳离子束的日常质量保证（QA）。
在超过 3 年的时间里获得了质子的日常 QA 趋势线，在超过 2 年的时间里获得了碳离子的日常 QA 趋势线。审查了关键的日常 QA 参数，即光斑大小和位置、射束范围、布拉格峰宽度、重合度（束流和成像系统等中心之间）、均匀性和剂量。
评估了质子和碳离子 QA 设备的性能。每日 QA 趋势线使我们能够检测到机器性能的漂移和变化。提供了公差和行动水平的定义，并与文献中使用的水平进行了比较。
该设备已成功在双粒子治疗设施中实施超过 2 年，用于常规日常 QA 活动。它提高了日常 QA 的效率，并提供了全面的 QA 流程。
