Abstract

The embodiment of the invention provides a radiographic image detector which comprises a substrate; an optical image detector located on the substrate, wherein the optical image detector comprises a plurality of arrays of periodically arranged photosensitive pixels; a pixelated shading structure located on the side, away from the substrate, of the photosensitive pixel, the shading structure comprises at least one shading layer, and each shading layer comprises at least one through hole. The detector also comprises a pixelated light condensation structure located on the side, away from the photosensitive pixels, of the shading structure, the light condensation structure comprises at least one convex lens, wherein the optical axis of the convex lens is perpendicular to the shading layer andpenetrates through the through hole; a radioactive ray conversion layer located on the side, away from the shading structure, of the light condensation structure and converts radioactive rays into visible light; and a light gathering structure which gathers the visible light which is emitted by the radiation conversion layer and is close to the optical axis to the through hole. According to the invention, the crosstalk phenomenon can be improved and the image resolution can be improved.

Description

technical field [0001] The invention relates to the technical field of image detection, in particular to a radiation image detector. Background technique [0002] Flat-panel radiation image detectors have been widely used in digital medical diagnosis and real-time monitoring of radiation therapy. This flat-panel image detector has the advantages of quickness, low cost, low exposure, high image quality, etc., and is convenient for data storage, transmission and calculation, and can be integrated into a digital medical system. With the development of technology, dynamic X-ray images have also become possible. They can not only be applied to large-scale medical imaging applications such as chest fluoroscopy and cardiovascular dynamic X-ray images, but also have gradually penetrated into small-area imaging and imaging applications such as dentistry. diagnostic applications. [0003] According to the detection principle and structure, flat-panel radiation image detectors can be...
