Daily volumetric imaging through cone-beam computed tomography (CBCT) has greatly impacted the roles and responsibilities of radiation therapists (RTTs). A CBCT eLearning module was developed at our cancer centre to equip RTTs with critical thinking skills and clinical judgement required in a CBCT guidance environment. This study aims to evaluate the effectiveness of the electronic module and its impact on the learner's outcome from the perspectives of various radiation therapy professions and to assess the applicability of the eLearning module to RTTs, oncologists, and physicists.
The module "Myths in Cone-Beam Computed Tomography Practice" was evaluated by participants from our in-house accelerated education program. A 21-item questionnaire was developed to assess the module effectiveness. Two cohorts of attendees from the in-house accelerated education program (19 oncologists, 14 physicists, 14 therapists) were asked to voluntarily complete the survey following review of the module. Data analyses were performed between groups to determine differences in their perceptions.
Twenty-one participants (5 oncologists, 3 physicists, 13 therapists) responded to the survey yielding a response rate of 44.68%. Survey responses indicate learners found the format user friendly, clear, and easy to navigate. All participants agreed that the electronic format of this module is conducive to learning with 60% agreement that this module is more useful than live sessions; 94.74% agreed that the module increases confidence in practicing image-guided radiation therapy.
This module is a useful resource for all disciplines of radiation medicine. While the electronic format of this module may be useful worldwide in centres requiring training of their employees in volumetric image-guided radiation therapy, live interactive sessions should supplement this training.
通过锥形束计算机断层扫描（CBCT）进行的每日容积成像对放射治疗师（RTT）的角色和职责产生了重大影响。我们癌症中心开发了一个CBCT电子学习模块，以使RTT具备在CBCT引导环境中所需的批判性思维技能和临床判断力。本研究旨在从各种放射治疗专业的角度评估该电子模块的有效性及其对学习者结果的影响，并评估该电子学习模块对RTT、肿瘤学家和物理学家的适用性。
来自我们内部加速教育项目的参与者对“锥形束计算机断层扫描实践中的误区”模块进行了评估。编制了一份包含21个条目的问卷来评估该模块的有效性。来自内部加速教育项目的两组参与者（19名肿瘤学家、14名物理学家、14名治疗师）在复习该模块后被要求自愿完成调查。对组间数据进行分析以确定他们认知上的差异。
21名参与者（5名肿瘤学家、3名物理学家、13名治疗师）回复了调查，回复率为44.68%。调查回复表明学习者认为该模块的格式用户友好、清晰且易于操作。所有参与者都认为该模块的电子格式有利于学习，60%的人认为该模块比现场授课更有用；94.74%的人同意该模块增强了在进行图像引导放射治疗方面的信心。
该模块是放射医学所有学科的有用资源。虽然该模块的电子格式在需要对员工进行容积图像引导放射治疗培训的中心可能在全球范围内都有用，但现场互动课程应作为此培训的补充。
