LIGHT CONVERSION APPARATUS FOR X-RAY IMAGING DETECTOR AND X-RAY IMAGING DETECTOR WITH THE SAME

摘要

The present invention relates to a light conversion device for an X-ray image detector and the X-ray image detector including the same. The light conversion device for the X-ray image detector converts X-ray passing through an object into visible ray and changes a light path of the visible rays by being included in the X-ray image detector. The light conversion device is formed in a hexahedron shape and includes a holder body in which an accommodation groove is formed on a vertex part; an installation surface formed along the outer circumference of the accommodation groove by being cut on the outer surface of the holder body at a predetermined length; a scintillator fixed to the installation surface facing the direction in which the X-ray passing through the object is radiated and converting the X-ray into the visible ray by being included in a plate shape; and a reflector changing the light path of the visible ray converted in the scintillator by being installed in the accommodation groove. According to the present invention, the installation surface is formed in the holder body in which the accommodation groove is formed, and the scintillator and the reflector are individually installed in the installation surface and the accommodation groove. A mask is installed on the outer surface of the holder body. The light conversion device can be easily and affordably manufactured in an ultra-miniature shape to be able to correspond to an optic device having a short operation distance and implementing high spatial resolution. A reflection film passing the X-ray through on one surface of the scintillator and reflecting the visible ray is included in order to improve the efficiency of light detection so that the present invention can implement high temporal resolution.
