    • An X-ray tube and an X-ray detector are supported by an arm in such a manner that a distance between the X-ray tube and an image reception plane of the X-ray detector can be changed. A grid is arranged on the image reception plane of the X-ray detector. The arm is supported by an arm support apparatus in such a manner that an angle of the arm can be changed. Moire image data files obtained by the grid are stored in a storage device in association with the distance between the X-ray tube and the image reception plane of the X-ray detector and the angle of the arm. Image data outputted from the X-ray detector is corrected by the moire correction circuit based on the moire image data selectively read from the storage device in accordance with the distance and the angle.

    • An X-ray diagnostic system is provided that is capable of fitting the vertical position of the X-ray tube to each mode of photography without being affected by the height of the ceiling. The X-rays irradiated from the X-ray tube and transmitted through the subject are detected, and photographed images are captured based on the detected X-rays; the system comprises a supporting member, an arm member, and a height adjuster; the supporting member is provided on the ceiling of a room, formed in a pillar shape, and configured in such a way that the entire length is vertically extended and shortened. The arm member has a base end section connected to the lower end portion of the supporting member and a tip section on which the X-ray tube is mounted. The height adjuster adjusts the vertical position of the X-ray tube by moving the tip section of the arm member relative to the supporting member.

    • When the electrode potential of a charge control electrode above a wafer is reduced, image brightness is reduced. A point of change in the image brightness is a switching point between a positively charged state of the image and a negatively charged state of the image, showing the weakly charged state of the image. By setting this point of change as an inspecting condition, the amount of electric charges on the surface of the wafer can be reduced, and stable wafer inspection can be performed. It is estimated that an applied voltage V1 in FIG. 14 corresponds to the point of the change and is roughly included in the voltage range of a region enclosed by a broken line in the vicinity of the applied voltage V1. Within this voltage range, the influence of charge on an inspection under the inspecting condition can be reduced.
