The effectiveness of using a Digital Imaging and Communications in Medicine (DICOM)-based interactive examination system in evaluating the readiness of first year radiology residents before taking overnight call in the emergency department (ED) was reported in part I of this article. This report describes technical aspects for the design and implementation of this system.
The examination system consists of two modules: Data Collection and Image Viewing. The Data Collection module was a personal computer (PC)-based DICOM storage server based on a free public domain software package, the Mallinckrodt Central Test Node. The Image Viewing module was a Java-based DICOM viewer created using another freeware package: zDicom ActiveX component.
The examination takes place once a year at the end of the first 6-month rotation. Cases selected for the examination were actual clinical cases according to the American Society of Emergency Radiology core curriculum. In the 3-hour timed examination, each resident was required to read the cases and provide clinical findings and recommendations. Upper-level residents also participated in the examination to serve as a control. Answers were scored by two staff radiologists.
We have been using this examination system successfully in our institution since 2003 to evaluate the readiness of the first-year residents before they take overnight call in the ED. This report describes a step-by-step procedure for implementing this system into a PC-based platform. This DICOM viewing software is available as freeware to other academic radiology institutions. The total cost for implementing this system is approximately 2000 US dollars.
本文第一部分报道了使用基于医学数字成像和通信（DICOM）的交互式检查系统评估放射科一年级住院医师在急诊科值夜班前准备情况的有效性。本报告描述了该系统设计与实施的技术方面。
检查系统由两个模块组成：数据收集和图像查看。数据收集模块是基于个人计算机（PC）的DICOM存储服务器，基于免费的公共领域软件包马林克罗特中央测试节点。图像查看模块是使用另一个免费软件包zDicom ActiveX组件创建的基于Java的DICOM查看器。
检查在第一年6个月轮转结束时每年进行一次。检查所选病例为根据美国急诊放射学会核心课程的实际临床病例。在3小时的定时检查中，要求每位住院医师阅读病例并提供临床发现和建议。高年级住院医师也参与检查作为对照。答案由两名放射科工作人员评分。
自2003年以来，我们一直在本机构成功使用该检查系统来评估一年级住院医师在急诊科值夜班前的准备情况。本报告描述了将该系统实施到基于PC的平台中的逐步程序。这种DICOM查看软件可供其他学术放射机构免费使用。实施该系统的总成本约为2000美元。
