Cooperative Grid Based Picture Archiving and Communication System

摘要

A Cooperative Grid Based Picture Archiving and Communication System (Grid PACS for short) is a multimedia (imaging) medical information archiving, communication and application system used in hospitals. Based on the existing PACS servers, workstations, or other networked multimedia image management systems, it adds and integrates grid-based network functionality into the existing image systems to form new grid-based image communication and management system.;It uses service-oriented and event-driven concepts and methods to design and implement a new grid-based image communication and management system to solve the problems encountered in distributing archived image information, coordinating work and managing in a virtually centralized way (Virtual Super-PACS) of different PACS or archiving systems under varied operating environments.

1. A master node in a cooperative grid based picture archiving and communication system with a three level working structure of agent nodes, client ends and the master node, the master node being responsible for the agent nodes and being connected to each of the agent nodes via a network, each agent node having an associated picture archiving and communications system (PACS), each PACS comprising an image database containing image data including image registration information, the master node comprising a computer processor and master software executable on the computer processor, wherein when the master software is executed by the computer processor, the master node performs the following steps:
(a) receiving via the network from one of the agent nodes a manifest having image registration information compiled from the image data for a plurality of images stored in the image database of the agent node's associated PACS, the image registration information in the manifest including, for each image, information sufficient to retrieve the image data for that image from the PACS's image database; (b) parsing the manifest to extract the registration information; (c) storing the registration information for the plurality of images in a master node database; and (d) when the master node receives a query for image data from a client end, searching the master node database to determine whether the image data is available in one of the PACSs, and if the image data is available in one of the PACSs, providing information to the client end sufficient to access the image data.
