1. X-ray imaging apparatus possesses:

  • Top board, the mounting subject;

    The X ray test section is made of the X-ray detector with the 1st field size and high-accuracy detector higher than above-mentioned X-ray detector resolution and that have the 2nd field size less than above-mentioned X-ray detector visual field;

    The X ray generating unit is to above-mentioned subject X-ray irradiation;

    Maintaining part keeps above-mentioned X ray test section and above-mentioned X ray generating unit opposed to each other;

    The image operation handling part generates based on the 1X ray image of above-mentioned X-ray detector with based on the 2X ray image of above-mentioned high-accuracy detector;

    Display part shows above-mentioned 1X ray image and above-mentioned 2X ray image;

    Region setting part shows the point of a part that is equivalent to above-mentioned 2X ray image or is equivalent to the zone of above-mentioned 2X ray image at above-mentioned 1X ray image, and mobile above-mentioned point or above-mentioned zone are set the position of above-mentioned high-accuracy detector;

    The coordinate difference of the position of the above-mentioned point of the position of the above-mentioned high-accuracy detector that position deviation calculating part, the center of obtaining above-mentioned 1X ray image and expression set or the approximate centre position of above-mentioned zone;

    AndMobile control division is controlled above-mentioned top board or above-mentioned maintaining part according to above-mentioned coordinate difference, so that the approximate centre position movement of above-mentioned 2X ray image is to the approximate centre of the image display area of above-mentioned display part.
