Dedicated digital projectional radiographic system

The authors developed an inexpensive, high-precision image digitization analysis, and communications system based on a linear array charge-coupled device scanner and Macintosh II computer. A NuBus interface was constructed to allow computer control of the array drive assembly and to transmit the digital image data from the array to the computer. With this system, they can digitize radiographs with spatial resolutions up to 3,000 X 4,000 pixels in approximately 1 minute. The images can then be viewed through a 1,024 X 780 window and processed using programs written in C. An Ethernet interface is used to send images rapidly to other computers within the hospital, and a high-speed (12,000 baud) telephone system is used to send images to attending physicians for home review
