<title>Dial-up switched 56,000 bits-per-second teleradiology system</title>

Abstract

A dial-up, wide bandwidth, digital teleradiology system was implemented between Irwin Army Community Hospital (Fort Riley, Kansas), Munson Army Community Hospital (Fort Leavenworth, Kansas), and the University of Kansas (KU) Medical Center (Kansas City, Kansas). A laser film digitizer and a gray scale display system were used at Irwin and Munson Army Community Hospitals to digitize radiographic films and display digital images. A laser film printer at KU Medical Center generates a film hardcopy of the transmitted digital data and an interactive gray scale display is used to review the digital image data. The communication system consists of dial-up, switched, multiple 56,000 bits per second digital channels, transmitting digital image data in parallel. Conventional radiographic films, multiformat camera films, and laser printed films from multimodality imaging systems-- computed tomography (CT), magnetic resonance (MR), ultrasound (US), nuclear medicine (NM), digital fluorography, and phosphor plate computed radiography (CR)--have been successfully digitized, transmitted, and laser film recorded or gray scale displayed. It is concluded that the implemented dial-up, wide bandwidth, multiple 56,000 bits per second digital teleradiology system provides clinically acceptable image quality reproductions.© (1992) COPYRIGHT SPIE--The International Society for Optical Engineering.
