Paper Abstract

The construction of a medical image communication network among hospitals in the Lansing, Michigan area demonstrates new opportunities for expanded relationships and services among hospitals, out patient clinics and associated professional groups. Routine clinical operation of the network commenced in May 1985. Three municipal CATV systems provide the data communication channels for rapid transfer of digital images to remote locations for viewing and archiving. Currently, reconstructed compressed computed tomography images are automatically transmitted in a few seconds from community hospitals to a centralized interpretation service. Broadband network equipment was designed and assembled that interconnects commercial CT scanners and display systems. The use of leased CATV bandwidth (3 MHz) is key to the economic and operational feasibility of the project. Both operating and equipment costs will be presented. Fluctuations in cable signal amplitudes and noise content, and a variety data error patterns occur on such a shared channel resource having thousands of attached users; this requires careful design attention. Various channel characteristics and performance experience with such a complex cable network will be reviewed. The clinical users have adapted surprisingly well to the new patterns of activity and communications.
