A TFT-PIN array substrate and an assembly structure for a flat-panel x-ray detector are provided to overcome the problem that the conventional scintillator substrate and TFT-PIN array substrate are neither penetrated by UV-light nor assembled by UV curable LOCA. The metal layer of the PIN photodiode of the TFT-PIN array substrate is perforated to have at least one hole, whereby UV-light can pass through the TFT-PIN array substrate to cure UV curable LOCA. Therefore, UV curable LOCA can be used as an adhesive layer in the assembly structure of a scintillator substrate and a TFT-PIN array substrate to promote the detective quantum efficiency and image quality of a flat-panel X-Ray detector.
X-RAY IMAGE SENSOR AND X-RAY IMAGE SENSOR SYSTEM USING THE SAME
(2015-04-16)
YANG KEI-HSIUNG
An x-ray image sensor and an x-ray image sensor system using the same is disclosed. The x-ray image sensor has a back-light unit emitting actinic and non-actinic lights. There is an x-ray-photoconductor-assisted liquid crystal light valve including an x-ray photoconductive unit to absorb x-rays passing through an object to be imaged and create a charge image corresponding to an image of the x-rays and a liquid crystal cell unit to convert the charge image into at least one optical image illuminated by the non-actinic light. The optical image is detected by an optical imager. The optical imager is coupled to a processor converting data of the optical image into picture archiving and communication system (PACS)-compatible format for further storages, distributions, and displays.
