This paper describes the background, purpose and design factors associated with a prototype, microprocessor-based slow-scan television (SSTV) system being developed to support the remote interpretation of radiographs. A video camera is used to capture the image of interest in the same manner as it is for standard television. Video input from the camera is processed to provide the best possible image to be stored in the input image digital storage memory. The input image is displayed and examined to determine that the desired image features are actually visible. The input image is transmitted to the output image storage memory via a simulated narrowband communications. This transmission is controlled by the LSI-11 microcomputer. The received image is by viewed by the radiologist on the output image display. In an interactive mode of operation the keyboard and trackball are used to control the LSI-11 microcomputer which, in turn, selects the amount and location of image data to be transmitted. The keyboard and trackball controller also provide the radiologist with the opportunity to manipulate the received image.
