Paper Abstract

Little technical information has been made available on CT image format or viewers. For large matrix displays (320 x 320 or 512 x 512), a high quality TV monitor with a bandwidth of 10 MHz or greater is required. If only a single field of a two to one positive interlaced TV monitor is displayed, an 875 line rate TV would be required in order to display the entire matrix. For image recording, a transparency system such as a multi-format unit or a 105 mm roll film camera will generally provide the best results. Finally, in order to improve the final CT image, various picture processing routines may be used. These include pre- and post-reconstruction smoothing, edge enhancement and image subtraction.
