Abstract: A teleradiology system for sending the raw data from a complete patient study to a remote location for a radiologist to make a final diagnosis. The system consists of two segments, a sending segment and a receiving segment. The sending segment consists of a universal floppy disk reading unit capable of reading raw data from a radiological device, (e.g., CAT Scanner, Nuclear Medicine Imaging device, Magnetic Resonance Imaging device, and the like) a personal computer, and a high speed modem. The receiving segment consists of a high speed modem to receive the data from the sending segment, a personal computer to control the receiving and manipulation of the data, and a high resolution monitor to view the images. The segments communicate through the modems and over existing telephone systems. At the remote location, the radiologist has the raw data and the capability of utilizing true windowing functions and true density values.
