X-RAY IMAGE INTENSIFIER AND APPLYING METHOD THEREOF TO DIGITAL X-RAY PHOTOGRAPHING SYSTEM

摘要

The present invention relates to a radiological image intensifier, and more precisely the luminescent screen of the intensifier. / p & & p & the thickness h of the layer of luminescent material on the edges of the screen 1, at 110 about the edge of the image field, is approximately 15 to 25 lower than its thickness h at the center of the screen. Thus, the length of the path of the x-rays in the luminescent material is substantially the same whatever the angle of incidence of the x rays on the screen and when the energy of the x-rays varies, the impact at all points of the screen varies in substantially the same manner. / p & & p & the screen according to the invention is especially used in radiology systems, 1984, or on several times the same image, by using different energies of x-rays.
