Abstract

UNLABELLED

RATIONALE AND OBJECTS: We describe a new web-based physics course for radiology residents preparing for the Exam of the Future (EOF).

MATERIALS AND METHODS

A course was developed with a total of 12 web-based modules. Six modules were focused on "imaging" and six on "radiation." A module was subdivided into nine short "nuggets." Traditional lectures were replaced by modules using prerecorded lectures (Tegrity) to a secure website (WebCT). Each module was accompanied by three quizzes, each consisting of ten questions designed to reinforce covered materials. All online modules were accompanied by a noon conference that employed an Audience Response System (Turning Point). Seventeen first-year residents over 2 consecutive years beginning in July 2010 took this new course, and participated in an anonymous online follow-up survey (Survey Monkey).

RESULTS

The recorded 12 modules had an overall average duration of 72 ± 19 minutes. Ten of 17 residents expressed a preference of 15 minutes for nugget duration. Highest personal assessment scores of each resident's understanding were obtained in human radiation risks and radiation protection. Residents considered supplemental noon conferences to be important for learning radiological physics. Satisfaction level was largely positive, with five residents highly satisfied, nine residents somewhat satisfied, two residents neutral, and only one resident somewhat dissatisfied.

CONCLUSIONS

Our Foundations of Radiological Physics course was well received and served as the springboard for mastering x-ray-based imaging modalities of radiography, mammography, fluoroscopy, interventional radiology, and computed tomography.

背景与目的

我们为准备未来考试（EOF）的放射科住院医师介绍一门新的网络放射物理学课程。

材料与方法

共开发了 12 个基于网络的模块。其中 6 个模块侧重于“成像”，6 个模块侧重于“辐射”。一个模块细分为 9 个简短的“知识点”。传统讲座被使用预先录制的讲座（Tegrity）代替，放置在一个安全的网站（WebCT）上。每个模块都附有三个测验，每个测验包含 10 个问题，旨在强化所学材料。所有在线模块都有一个中午会议，使用观众应答系统（Turning Point）。2010 年 7 月开始的连续两年中，17 名第一年住院医师参加了这门新课程，并参与了一项匿名在线后续调查（Survey Monkey）。

结果

12 个记录的模块总时长平均为 72±19 分钟。17 名住院医师中有 10 名更喜欢 15 分钟的知识点时长。每位住院医师对人类辐射风险和辐射防护的理解的个人评估得分最高。住院医师认为补充性的中午会议对学习放射物理学很重要。满意度水平总体上是积极的，有 5 名住院医师非常满意，9 名住院医师有些满意，2 名住院医师中立，只有 1 名住院医师有些不满意。
