Remote sites access images over 56 kb/s link.

Remote Sites Access Images Over 56 kb/s Link Five medical centers around the country are poised to begin transmitting nuclear medicine images between Macintosh II PCs, over US Sprint's Virtual Private Network 56 service.

The technology should improve diagnoses and patient treatment. Outlying medical facilities could link to larger health care centers so physicians far apart can consult with complete information on complex cases.

Computers, modems, and X-ray film are not needed with the process. Images and data go directly from a gamma camera linked to a Mac over the fiber VPN 56 network.

Transmissions cross the network at the price of a long-distance call.

Dr. James Lear of the University of Colorado Health Sciences Center predicts the process will revolutionize radiologic and nuclear imaging and data transmission in health care.
