美国近距离放疗学会医学物理住院医师培训共识指南第一部分：高剂量率远程后装近距离放疗
该共识由15名美国放射学委员会认证的医学物理师制定，针对高剂量率近距离放疗的医学物理住院医师培训，定义了满足NRC授权医学物理师（AMP）要求的两个培训级别。Level I侧重基础能力与QA，要求至少10例3D计划病例（其中6例涉及2个或以上通道）；Level II侧重工作经验，要求至少15例3D计划病例，包括至少7例组织间插植（允许混合施源器）且单通道病例不超过5例。
要点
- Level I要求至少10例3D计划病例，其中6例涉及2个或以上通道。
- Level II要求至少15例3D计划病例，包括至少7例组织间插植且单通道病例不超过5例。
- 培训需覆盖QA设备需求、全部QA程序、屏蔽原则、法规剂量限值和应急程序。
核心结论
- 适当的培训和经验对高剂量率近距离放疗至关重要，两个级别为学员获得AMP资格并独立实践提供了清晰的结构化路径。
研究设计与样本
- 采用名义群体技术，由来自14个机构（包括学术中心和独立诊所）的15名美国放射学委员会认证医学物理师组成专家小组制定共识建议，并与NRC 313A表（AMP）对齐。
诊断标准与关键数值
- Level I针对NRC培训要求，学员应理解QA设备需求、执行或描述所有QA程序，并展示屏蔽原则、法规剂量限值和应急程序的知识。
- Level I临床培训应包括至少10例3D计划病例，其中6例涉及2个或以上通道。
- Level II针对NRC工作经验要求，学员必须满足所有Level I标准并能履行Level I临床职责，为新施源器或技术提供QA和临床指导，以及为员工提供应急培训。
- Level II经验要求至少15例3D计划病例，包括至少7例组织间插植（允许混合施源器）且单通道病例不超过5例。

PURPOSE: To provide recommendations on training guidelines for therapeutic medical physics residents, including standards for satisfaction of the Nuclear Regulatory Commission (NRC) Authorized Medical Physicist (AMP) high-dose-rate (HDR) brachytherapy training and experience requirements.
METHODS AND MATERIALS: Following the Nominal Group Technique, an expert panel of 15 American Board of Radiology-certified medical physicists from 14 institutions, including academic centers and freestanding clinics, developed consensus recommendations that align with NRC form 313A (AMP).
RESULTS: Training and experience requirements were defined at two levels. Level I addresses NRC training requirements and focuses on foundational HDR brachytherapy competencies. Trainees should understand quality assurance (QA) equipment needs, perform or describe all QA procedures, and demonstrate knowledge of shielding principles, regulatory dose limits, and emergency procedures. Clinical training should include at least 10 3D planned cases, 6 involving 2 or more channels. Level II addresses NRC work experience requirements. Trainees must meet all Level I standards and be capable of performing Level I clinical duties, providing QA and clinical guidance for new applicators or techniques, as well as emergency training for staff. Level II experience requires a minimum of 15 3D planned cases, including at least seven interstitial procedures (hybrid applicators allowed) and no more than five single-channel cases.
CONCLUSIONS: Proper training and experience are essential for HDR brachytherapy. The two levels defined in this work offer a clear, structured pathway for trainees to achieve AMP status and ensure readiness for independent practice.
