The constructions and the fundamental studies for the high-speed x-ray television (TV) system utilizing a flash memory device in conjunction with a high-speedc harge-coupled-devic(eC CD)c amera are described. This system can be applied to low-noise type flash x-ray generators and consisted of the following essential components: a repetitive flash x-ray generator, an image intensifier (II), a highspeed CCD camera, a flash memory device, a timing device between the x-ray generator and the flash memory device, and an image processor. The radiographic images from an II were taken by a CCD camerai n conjunctionw ith a flash memoryd evice. Theses troboscopici magesw erer ecordedb y a video tape recorder (VTR) and were reproduced and analyzed by the image processor having a color printer. The flash memory device was connected to the pulsed x-ray generator through a timing device utilizing a light coupling system. The frame speed of the TV system was controlled by the flash memory system in conjunction with a repetitive flash light system. When a home-video system was employed, the maximum frame speed was 30 fps (Hz).
