Distributed image diagnosis device in the network environment

本研究的目的是：（1）实现一种便携式影像诊断仪;（2）定义最佳的影像诊断多媒体数据库结构;（3）建立计算机辅助诊断系统。我们研制了一种基于个人计算机的图像诊断仪，它通过SCSI接口与3.5英寸磁光盘相连，并通过网络接口与数据库服务器通信。该设备的重量约为3 Kg，并且该诊断设备难以携带，因为该设备不是一体式的。实现了从MOD中读取图像的图像显示，并定义了包含图像和人口统计数据的多媒体数据库。我们可以从这个收集了两万个病例的多媒体数据库中快速检索图像。最后提出了计算机辅助诊断的方法：（1）从过去的病例中检索相似病例，（2）图像的显示，（3）评价当前病例与检索到的病例之间的相似性。同时开发了关键词检索功能，可以通过关键词检索到相似的案例.我们使用HTML（超文本标记语言）安装和评估超文本参考系统。通过对近两年来的研究工作的总结，我们基本上完成了课题的研究目标，但认为还需要多媒体数据库的开发和计算机辅助诊断的有效性。

Aims of this research are (1) the implementation of a portable image diagnosis device, (2) the definition of the optimal multi-media database structure for image diagnosis, (3) the establishment of the computer assisted diagnosis. We developed the personal computer based image diagnostic device which is connected to 3.5 inch magneto-optical disk through the SCSI interface and communicated to the database server through network interface. The device's weight is about 3Kg and the this diagnosis device is difficult to carry, because the device is not all-in-one type. We implemented the image display which read out images from a MOD.We also defined the multi-media database which contains an image and demographic data. We could quickly retrieve the image from this multi-media database which collected twenty thousand cases. But we have to study the further optimization of structure in the motion images and the sound database.Finally the methods we used for the computer assisted diagnosis are (1) the retrieval of the similar cases from the past cases, (2) the display of the images, (3) evaluation of the similarity between the present case and retrieved case. Also we developed the keyword searching which enable to retrieve the similar case by the keyword. We installed and evaluated the hyper text reference system by using HTML (Hyper Text Markup Language). As we summarized the 2 years-research, we have alomst finished the aim of research, but we think that we need to the develop of multi-media database and effectiveness of the computer assisted diagnosis.
