To present the results and discuss potential insights gained through surveys on reference dosimetry practices.
Two surveys were sent to medical physicists to learn about the current state of reference dosimetry practices at radiation oncology clinics worldwide. A short survey designed to maximize response rate was made publicly available and distributed via the AAPM website and a medical physics list server. Another, much more involved survey, was sent to a smaller group of physicists to gain insight on detailed dosimetry practices. The questions were diverse, covering reference dosimetry practices on topics like measurements required for beam quality specification, the actual measurement of absorbed dose and ancillary equipment required like electrometers and environment monitoring measurements.
There were 190 respondents to the short survey and seven respondents to the detailed survey. The diversity of responses indicates nonuniformity in reference dosimetry practices and differences in interpretation of reference dosimetry protocols.
The results of these surveys offer insight on clinical reference dosimetry practices and will be useful in identifying current and future needs for reference dosimetry.
展示通过参考剂量测定实践调查所获得的结果并讨论潜在的见解。
向医学物理师发送了两份调查问卷，以了解全球放射肿瘤学诊所参考剂量测定实践的现状。一份旨在提高回复率的简短调查问卷在网上公开，并通过美国医学物理学家协会（AAPM）网站和一个医学物理师列表服务器进行分发。另一份复杂得多的调查问卷则发送给了一小部分物理师，以深入了解详细的剂量测定实践。问题多种多样，涵盖了诸如射线质规范所需测量、吸收剂量的实际测量以及诸如静电计和环境监测测量等所需辅助设备等参考剂量测定实践主题。
简短调查问卷有190名受访者，详细调查问卷有7名受访者。回答的多样性表明参考剂量测定实践存在不一致性以及对参考剂量测定协议的解释存在差异。
这些调查结果为临床参考剂量测定实践提供了见解，并将有助于确定参考剂量测定当前和未来的需求。
