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 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 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 an image from a client end, searching the master node database to determine whether the image is available in one of the PACSs' image databases, and if the image is available in one of the PACSs' image databases, providing information derived from the registration information for the image received from the agent node associated with that PACS to the client end sufficient to access the image in the PACS's image database.
