Abstract:
1. A fluoroscopic apparatus comprising: X-ray emission means for irradiating a subject with X-rays; narrowing means for limiting an X-ray irradiation range by changing an opening; X-ray image detecting means for picking up the X-rays which have been emitted from the X-ray emission means and have passed through the subject into the image of picture signals; reading and computing means for reading the picture signals pixel-by-pixel from the X-ray image detecting means, adding picture signals of at least one or more pixels and outputting them; and control means for controlling an irradiation condition of the X-ray emission means and adding method in the reading and computing means so as to be interlocked with an opening information of the narrowing means, wherein the control means decreases current flow into a tube of the X-ray emission means and increases a number of pixels to be added, in accordance with an increment of a size of a field to be irradiated with X-rays.
