PCT No. PCT/FI95/00193 Sec. 371 Date Dec. 4, 1996 Sec. 102(e) Date Dec. 4, 1996 PCT Filed Apr. 7, 1995 PCT Pub. No. WO95/27922 PCT Pub. Date Oct. 19, 1995An apparatus for making X-ray images includes an X-ray source which is controlled by an X-ray source control. A luminescent screen provides a visible image based upon X-rays transmitted by the X-ray source. A CCD camera receives and stores the visible image. Imaging optics including a mirror reflect the visible image to the camera without splitting the visible image into parts. A photosensor is in optical communication with the luminescent screen and is separate from the CCD camera. The photosensor is positioned such that an illumination power of the luminescent screen falls on the photosensor practically from within an area of an entire portion of the visible image. A computer and control connectable to the X-ray source control for adjusting exposure of the apparatus is connected to the photosensor.
