The development of the medicaltele-education system supporting multimedia applications, which is open to the regional students and doctors.

开发了支持静态图像和动态图像多媒体应用的医学远程教育系统。本系统不仅对医学生开放，而且对希望学习当前医学课题的从业人员开放，作为经常性的研究生医学教育之一。在2001年（本研究的第一年），由于只能使用ISDN(64kbps)，其安全性与1999年推出的诊断远程医疗系统相同。当时，由于带宽较窄，资料仅限于静止图像，通过扫描仪数字化为JPEG图像文件。在将图像注册到数据库服务器时，需要患者的姓名和身份证号、主诉、科室、图像的种类和模式、5个字符以内的关键字、评论和诊断要点。在客户端的Web视图中，不会显示患者的姓名和ID号。可以通过参考键检索图像。在本研究的最后一年（2002年），当我校有了宽带通信系统时，对系统进行了定制，以支持mpeg2格式的运动图像。同时，除了数据库服务器外，还引入了Web服务器，网络配置也发生了变化。虽然与JPEG文件相比，在Web上显示缩略图比较困难，但我们成功地使用了免费软件（Quick Time）来显示静态缩略图。该系统还通过应用可以加密html文件的软件（由另一个基金）来防止图像的二次使用。综上所述，在宽带通信网络迅速普及的情况下，该系统在医学研究生教育中具有广泛的应用价值。

The medical tele-education system supporting multimedia applications including both still images and moving pictures is developed. This system is designed to be open not only to the medical students but to practitioners who hope to learn current medical topics as one of the recurrent post-graduate medical education. In 2001 (the first year of this research), as we could utilize only ISDN(64kbps), the security was confirmed as same as the telemedicine system for diagnosis which was introduced in 1999. At that time, the materials were confined to the still images and were digitized as JPEG image files by a scanner because of the narrow band. In registering the images to the database server, patients' name and ID number, chief complaint, department, the sort of the images and modalities, the key five words up to ten characters, comments, and key points of the diagnosis are required. On the Web view on the clients, patients' name and ID number are never displayed. The images can be retrieved by reference keys. In the final year of this research (2002) when the broadband communication system was available in our university, the system was customized to support the moving pictures(MPEG 2). Simultaneously, the Web server was introduced apart from database server and the network configuration was also changed. Although it was difficult to show the thumbnail images compared with JPEG files on the Web, we succeeded to display the still thumbnail by using the free software (Quick Time). The system was also designed to prevent the secondary usage of the images by applying the software which could encrypt the html files (by another fund).In conclusion, this system is widely useful in both pre-graduate and post-graduate medical education through broadband communication network spreading rapidly.
