Abstract：
BACKGROUND: Individual professions seek to define their professional practice through competencies which describe the behaviours and technical attributes to perform effectively within role. Professional body and regulatory frameworks define universal standards for radiography but there is limited evidence of the technical competencies expected of the workforce in Computed Tomography (CT). This study aimed to address this gap by agreeing the essential competencies for the early career radiography workforce who have CT as part of their clinical responsibilities. This is the first step in developing a competency framework for CT across all radiography expertise levels.
METHODS: A modified e-Delphi study was used to identify and gain agreement on essential practice competencies for this group. Structured surveys over two rounds were completed by an expert panel with CT knowledge and experience. Participants were asked to rate the essentiality of competencies for the novice CT workforce. Structured feedback was provided between surveys for consensus building, defined by the content validity ratio (CVR).
RESULTS: Survey responses were received from 34 participants across different diagnostic imaging roles and settings. A total of 56 competency statements were agreed as essential for the early career CT workforce, including some appropriate to assistant radiographer practitioner roles. Competencies could be divided into those that were relevant to diagnostic radiography but could be applied to the CT setting (n = 32) and technical attributes unique to the CT context (n = 24).
CONCLUSIONS: CT competencies for this group centre around understanding technical concepts of image formation and image quality optimisation; patient preparation and contrast media administration.
CONCLUSIONS: The competencies presented in this research represent the agreed minimum standards for the workforce in CT. Further work is required to validate competencies in practice.

摘要：
背景：个人职业试图通过能力来定义他们的职业实践，这些能力描述了在角色中有效执行的行为和技术属性。专业机构和监管框架定义了射线照相术的通用标准，但对于计算机断层扫描（CT）员工的技术能力预期的证据有限。这项研究旨在通过同意将CT作为其临床职责一部分的早期职业射线照相工作者的基本能力来解决这一差距。这是开发所有射线照相专业知识级别的CT能力框架的第一步。
方法：使用改良的e-Delphi研究来确定该组的基本实践能力并达成共识。具有CT知识和经验的专家小组完成了两轮的结构化调查。要求参与者对新手CT员工的能力进行评估。调查之间提供了结构化的反馈，以建立共识，由内容有效性比率(CVR)定义。
结果：来自不同诊断成像角色和设置的34名参与者的调查回复。共有56份能力声明被认为是早期职业CT员工所必需的，包括一些适合放射技师助理的角色。能力可以分为与诊断射线照相相关的能力，但可以应用于CT设置（n=32）和CT上下文特有的技术属性（n=24）。
结论：该组的CT能力集中在理解图像形成和图像质量优化的技术概念；患者准备和造影剂管理。
结论：本研究中提出的能力代表了CT劳动力的商定最低标准。需要进一步的工作来验证实践中的能力。
