Abstract
The present invention refers to X-ray technology and is intended for application in medical X-ray units. A small-sized X-ray image detector is created, wherein the photoelectric sensor is protected against X-rays, but the capability of obtaining high-quality images is retained. The X-ray image detector incorporates a housing 1 with a wall 2 radiotransparent, in which a fluorescent screen 3, an optical system 4 and a CCD matrix 5 are installed; protective screen functions are provided by the lenses incorporated in the optical system, at least ten of which shall have refraction index no less than 1.6, and the fluorescent screen attenuates X-rays by 30%.
Claims3
