The present invention relates to a high-energy X-ray imaging device that is suitable for precise medical diagnosis and capable of enhancing the accuracy of nondestructive examinations. The high-energy X-ray imaging device of the present invention includes an electron-circulating type high luminance X-ray generator and a two-dimensional X-ray detector that is sensitized for high-energy X-rays. The electron-circulating type X-ray generating device consists of a tinytarget together with a LINAC or microtron injector and a synchrotron. The synchrotron stores electrons, and electrons are bombarded against a tinytarget placed on the electron orbit to generate high-energy X-rays. The means to sensitize the two-dimensional X-ray detectors consists of a thin film made of lead or other heavy elements. This thin film is placed in front of and in close contact with the two-dimensional detector, such as X-ray film. The X-ray image thus generated is a transmissive image.
