Abstract
The storage of large amounts of digital image data and the communication of the images within a hospital are major problems in the development of a Picture Archiving and Communications System (PACS). Image compression reduces both the problems of storage capacity and of the image transmission rate by approximately a factor 12. It is shown that the use of memory buffers at different hierarchical system levels provides for an additional reduction in the required transmission rate. In order to determine the communication rates and number and size of the buffers, the PACS has been modelled by a system of queues and servers. Queueing models can be analysed by means of computer simulation but also mathematically. Examples of mathematical analysis are given and a simplified model of the department of radiology is evaluated.
