项目摘要

We developed two medical image display devices that are connected by a local area network (LAN). We use them for diagnostic purpose and discuss the problems among the coordinated diagnostic image manipulation. The software was written by Java language. A CT image (512x512x10bit) was displayed in 6 seconds by a personal computer (300MHz Pentium II, 128MB memory, Windows95, JDK1.2 environment). We could alter the window level and window center within one seconds. The protocol of teleradiology was designed independently and the commands of session were implemented in the server-client environment. We reduced the transfer of the patient information via network for the patient's privacy and the system performance.We also developed the image database for the teleradiology. The number of images reached 1000 and images were archived through the film digitizer and CT scanner. We implemented a image display software and a coordinated diagnostic image process software.We studied the feasibility and effectiveness of these system and found that the image display function and the shared cursor function was satisfactory. But the layout of image windows was not coordinated. The appearances of windows were different between two image display devices. In future, we have to improve this point.In the clinical aspect, this system showed the good presence instead of the real interview, we could discuss the case accurately by the coordinated image display function. But the speed of image display is not satisfactory and the image display functions were not so convenient. There is plenty of room for improvement in the system.

我们开发了两种通过局域网连接的医学图像显示设备。我们将它们用于诊断目的，并讨论了协调诊断图像处理中的问题。软件采用Java语言编写。用个人计算机（300MHz Pentium II， 128MB内存，Windows95, JDK1.2环境）在6秒内显示一张CT图像（512x512x10bit）。我们可以在一秒钟内改变窗户的水平和中心。远程放射学协议独立设计，会话命令在服务器-客户端环境下实现。为了患者的隐私和系统的性能，我们减少了患者信息通过网络的传输。我们还开发了远程放射学图像数据库。图像数量达到1000张，并通过胶片数字化仪和CT扫描仪进行图像存档。我们实现了一个图像显示软件和一个协调的图像诊断处理软件。我们研究了这些系统的可行性和有效性，发现图像显示功能和共享光标功能是令人满意的。但图像窗口的布局不协调。两种图像显示设备的窗口外观不同。在未来，我们必须改进这一点。在临床方面，该系统较好地代替了真实的访谈，通过协调的图像显示功能可以准确地讨论病例。但图像显示速度不理想，图像显示功能不方便。这个系统还有很大的改进空间。
