  • Teleradiology system
    Patent number: 4910609
    Abstract: A teleradiology system capable of scanning X-ray images and the like and transmitting the scanned images to various locations is disclosed. The images may be compressed for storage or transmission. Compressed images can be transmitted much more quickly and take up much less space than uncompressed images. Compressed images can be expanded for, among other things, viewing. The compressor/expander and input/output devices reside on a bus structure in such a manner that digital image data can be selectively passed between the compressor/expander and the various input/output devices.
