A computer-assisted didactic interactive system for radiology is described; it was implemented on a widely available, cost-effective personal computer with advanced graphic features. A set of suitable CT images was selected and digitized with a specific software that also allowed to process the acquired images. After adding graphic and textual comments, the images were ready to be put in the tutorial. A second software tool was used to manage the image display and to control the correct sequence of the interactive steps of the tutorial. A series of computer-driven multiple-choice questions was prepared to provide the user with a tool improving his/her knowledge of the topics covered by the system, in a simple and unconventional way. The tutorial was designed so that both the absolute number and the percentage of correct answers can be displayed and the critical evaluation of incorrect answers is automatically performed; in the end, the system goes back to the first screen and the tutorial can be run again. The system performance is good with standard hardware; it can be markedly improved with the integration of peripherals--i.e. hard disk. In the next future, the commercial availability of more advanced storage media (videodisks and optical disks) will dramatically improve the archiving capacity and will reduce access times.
本文描述了一种用于放射学的计算机辅助教学互动系统；该系统在一台具有先进图形功能、广泛可用且经济高效的个人计算机上实现。选择了一组合适的CT图像，并用特定软件进行数字化处理，该软件还允许对采集的图像进行处理。在添加图形和文本注释后，这些图像即可用于教程。使用第二个软件工具来管理图像显示并控制教程互动步骤的正确顺序。准备了一系列计算机驱动的多项选择题，以一种简单且非传统的方式为用户提供一个工具，帮助其提高对系统所涵盖主题的了解。该教程的设计使得能够显示正确答案的绝对数量和百分比，并自动对错误答案进行批判性评估；最后，系统返回第一个屏幕，教程可以再次运行。该系统在标准硬件上性能良好；通过集成外围设备（即硬盘），其性能可得到显著提升。在不久的将来，更先进存储介质（视频磁盘和光盘）的商业可用性将极大地提高存档容量并减少访问时间。
