Network data rate requirement analysis for picture archiving and communication systems

In this paper, the PACS network data rate requirement in a radiology department is discussed. The network data transmission rate under real data traffic in a medium-size hospital is evaluated using a simulation study. The network is assumed to be a circuit switching network. A preloading system, in which each workstation has local storage to store the next procedure, is assumed, and the network transmission rate which satisfies the response time of this system is obtained.

A high speed integrated computer network for picture archiving and communication system (PACS)

The functional and operational requirements for an integrated computer network to transmit image, text, voice, and image pointing overlays are presented, and the data traffic handling of each data type is discussed. A 200-Mbs fiber optic computer network was designed based on the presented PACS network requirements and the data traffic. The characteristics, protocols, and implementation feasibility of this network are summarized. These integrated PACS network can be used for a global PACS (GPACS). The GPACS will allow the exchange of images and patient information and will provide real-time consulting facilities among radiologists and physicians throughout the world.<<ETX>>
