In addition to a written report, ultrasound findings also require picture documentation. Cuts in physician fees warrant optimal cost-effectiveness in ultrasound documentation. Of the presently available equipment for permanent image recording off the monitor and direct electronic recording the following are to be discussed and compared: Polaroid recording, X-ray film, 35 mm roll film, dry silver paper, video-tape, floppy-disc, optical disc recorder and electronic still camera. The costs per picture, including investment and operating costs in relation to annual number of examinations, are calculated for the various systems.
