A new method has been developed for multimedia enhancement of electronic teaching files created by using the standard protocols and formats offered by the Medical Imaging Resource Center (MIRC) project of the Radiological Society of North America. The typical MIRC electronic teaching file consists of static pages only; with the new method, audio and visual content may be added to the MIRC electronic teaching file so that the entire image interpretation process can be recorded for teaching purposes. With an efficient system for encoding the audiovisual record of on-screen manipulation of radiologic images, the multimedia teaching files generated are small enough to be transmitted via the Internet with acceptable resolution. Students may respond with the addition of new audio and visual content and thereby participate in a discussion about a particular case. MIRC electronic teaching files with multimedia enhancement have the potential to augment the effectiveness of diagnostic radiology teaching.
一种新方法已被开发出来，用于对通过使用北美放射学会医学影像资源中心（MIRC）项目提供的标准协议和格式创建的电子教学文件进行多媒体增强。典型的MIRC电子教学文件仅由静态页面组成；通过这种新方法，可以将音频和视频内容添加到MIRC电子教学文件中，以便为教学目的记录整个图像解读过程。借助一个高效的系统来编码放射影像屏幕操作的视听记录，生成的多媒体教学文件足够小，可以以可接受的分辨率通过互联网传输。学生可以通过添加新的音频和视频内容做出回应，从而参与关于特定病例的讨论。具有多媒体增强功能的MIRC电子教学文件有可能提高诊断放射学教学的效果。
