两种基于WEB的医学影像传输和显示系统设计与评估

Design and Assessment of Two Medical Image Transmission and Display Systems based—on WEB

目前,在基于Web的医学图像传输显示领域中,存在多种技术,如ACTIVE-X HTML、Flash、HTML5等。不同技术在不同的网络环境下表现出不同的特点。对两种基于Web的医学影像传输显示系统进行了设计和评估,第一种是瘦客户端系统,其工作原理是基于HTML的瘦客户端与具有WADO接口的PACS Web服务器进行数据交换,传输的影像格式为JPEG或PNG;第二种是胖客户端系统,工作原理是富客户端,如ActiveX控件、HTML5或FLASH RIA程序与具有WADO接口的PACS Web服务器进行数据交换,传输的影像格式为非压缩DICOM,压缩格式的DICOM和JPIP码流。经测试,在不同网络环境下,两种系统各有优缺点。

Currently, in Web-based medical image transmission and display field, there are various technologies, such as ACTIVE-X HTML, Flash, HTML5, etc. DifFerent technology will present different characteristics under different network environment. The paper designed and assessed two Web-based medical image transmission and display systems. One is Thin Client system and its work principle is that HTML-based Thin Client exchanges data with PACS Web server containing WADO port, and the format of transmission data is JPEG and PNG. The other is Fat Client system and its work principle is that Fat Client, such as ActiveX, HTML5 or FLASH RIA programs, exchanges data with PACS Web server containing WADO port, and the format of transmission data is uncompressed DICOM, compressed DICOM and JPIP code stream. Through testing, it Found the advantages and disadvantages of both systems under different network environment.
