We have developed a cineradiography technique which will produce six pictures each on a separate piece of film, with framing rates up to 100,000 framessecond. The system utilizes six 150 keV flash x-ray tubes mounted side by side in one head. X-rays are converted to light by a single x-ray image intensification screen with rapid phosphor decay. The x-ray screen is viewed through six individually adjustable lenses by six, gated image intensifier tubes with light amplification of 15,000. Output from the tubes is recorded on Polaroid film. The x-ray flash duration of 70 nanoseconds per tube determines exposure time.
