PACS Controller and Image Archive Server

PACS controller - consists of hardware and software architecture, directs the data flow in the entire PACS by using interprocess communication among major processes

Archive server - hierarchical image storage management system for short-, medium-, and long-term image archiving.

Image Management Design Concept

Two major aspects to be considered:

1. data integrity - no loss of images once they are received by the PACS from the imaging systems
2. system efficiency - minimizes access time of the images at the display workstations

To achieve data integrity, PACS always has to retain at least two copies of an individual image on seperate storage devices until the original image has been archived successfully to the long-term storage device. This is achieved using PACS intercomponent communication.

Four components of the PACS controller and archive server:

1. archive server
2. database
3. digital linear tape (DLT)
4. communication network
