Patent ID: 8837671

Claim:
Radiographic apparatus comprising: a radiation source that moves freely along a given direction while applying radiation, a collimator for collimating radiation to generate fan shape radiation beams; a radiation detecting device for detecting the radiation beams; and a main controller comprising a CPU, wherein the CPU comprises a program that moves the radiation source along the given direction, provides for intermediate images to be continuously taken over an imaging range, each of the intermediate images having a portion of the imaging range falling thereon being superimposed on one another, and provides for a radioscopic image having the imaging range falling thereon to be generated, and wherein letting one forward end of the radiation detecting device in the given direction be a detecting device forward end, the other backward end of the radiation detecting device in the given direction be a detecting device backward end, one front end within the imaging range in the given direction be a range front end, and the other rear end within the imaging range in the given direction be a range rear end, the CPU comprises a program that aligns the detecting device forward end with the range front end in the given direction upon starting taking of the intermediate images, whereby an area irradiated with radiation on the radiation detecting device is located adjacent to the detecting device forward end, and that aligns the detecting device backward end with the range rear end in the given direction upon completing taking of the intermediate images, whereby the area irradiated with radiation on the radiation detecting device is located adjacent to the detecting device backward end, each of the intermediate images being narrower than the entire radiation detector relative to the given direction.
