A fundamental requirement for providing cost-effective solution to our growing health care predicament is the deployment of high-speed medical information network infrastructure that will support integration of multimedia medical information from diverse sources and will provide a unified view of all the available health care resources. Broadband communication networks will play a significant role towards the realization of a widely and uniformly available cost-effective health care system. The volume of medical images, which are essential aids for modem-day health care systems, has been rapidly increasing due to a growing number of patient exams performed and due to the availability of a more diverse range of imaging modalities. As a result, distribution, storage and management of image information has become a major issue in the health care industry. In a typical 600-bed hospital over one million images are generated annually requiring about two Terabytes of storage capacity. Bulk of this image volume is from X-Ray films requiring approximately 1.5 Terabytes of storage space annually. However, as MRI and CT exams become more common, greater number of images will be generated per exam thereby causing a significant growth in the image storage and distribution requirements. A well developed PACS (Picture Archiving and Communications System) will be able to surpass the current image-based diagnostic capabilities of a medical establishment and will be able to take advantage of new advanced technologies such as computer-aided-diagnosis, multi-modality display, and image enhancement and distribution. This will not only make the diagnosis process more accurate and timely but it will also be cheaper than the conventional "hard-copy" approach. Thus, communication networks are essential for efficient medical information archiving, distribution, remote medical consultation, medical tele-education and making available health care at home. However, these medical applications require storage and fast delivery of high volume of real-time multimedia traffic over local, metropolitan or wider areas. In this work we present our initial effort in developing a scalable and modular network architecture for cost-effective medical communication system providing real-time universal access in multimedia format. Target applications of such an integrated network design include telemedicine, teleradiology, electronic claims processing and supply ordering, teleconsultation, and home patient monitoring.
