Abstract

At present the management of radiological information is done manually in most hospitals. Images from the digital modalities (e.g. Computer- tomography scanners, X-ray machines) are converted into films and stored in a room. These films are then distributed manually and interpretation is done by reading the films through light boxes. With the advances in semiconductor technology and digital processing techniques it is now possible to automate these operations by using a digital system for archiving and communication of images. A Picture Archiving and Communication System (PACS), is a digital system for acquiring, storing, moving and displaying picture or image information .These systems are highly dependent on the new technology for mass storage of data on optical disks. In the medical environment, the ultimate goal of using digital images and PACS is tohave a radiology department without filmjackets 2,3 A typical PACS consists of a database of medical images, display stations, acquisition systems and the communications medium. There are two possible architectures for PACS, one is the distributed PACS where all the modules are linked together through a high speed communication medium, and the other is a centralized PACS where the acquisition nodes and the display stations are part of the system which comprises the image database 4. In this paper we present analytical queueing models of distributed PACS used in the medical environments. These models are for the image database, the picture viewing stations, and the communication channels.
