Abstract
When "fluoroscopy" is specified, a little amount of X rays are irradiated successively, and an X-ray image is reflected from rotating mirrors to enter a fluoroscopic camera head provided with FTCCD. The FTCCD can obtain a fluoroscopic image as a moving picture because successive imaging is possible in a frame rate. Moreover, when "radiography" is specified, great amounts of X rays are irradiated at one shot, and an X-ray image is reflected from the rotating mirrors to enter a radiographic camera head provided with FFTCCD. The FFTCCD is provided with pixels with large pixel size whose number is increased, and thus a high-definition radiographic image as a still picture can be obtained without using an X-ray film.
