PACS系统的迅速发展已引起医院临床科室和放射科的极大重视。本文介绍一种适合于医院影像科的经济实用的局域网 (L AN) ,其影像工作站的硬件和软件配置 ,依托于医院信息管理系统 (HIS) ,省去了昂贵的服务器和交换机 ,即能直接采集 X线 ,CT,B超 ,MRI等图像的各种视频信号 ,通过网络传输 ,临床科室可迅速调阅各工作站上的图文资料 ,从而实现医学影像资源共享 ,提高诊断和治疗效率 The rapid development of the PACS system has drawn great attention from hospital clinical departments and radiology departments. This article describes an economical and practical local area network (L AN) suitable for hospital imaging departments. The hardware and software configuration of the imaging workstation relies on the hospital information management system (HIS), eliminating the need for expensive servers and switches. Acquire various video signals of X-ray, CT, B-ultrasound, MRI and other images, and transmit them through the network. The clinical department can quickly access the graphic materials on each workstation to achieve the sharing of medical image resources and improve the efficiency of diagnosis and treatment.
