一种CT平板探测器及其CT机设计构想

Design Concept of CT Plate Detector and CT Machine

因薄膜晶体管迁移率过低,普遍认为无法将平板探测器应用于CT机。现有的研究方向是寻找更高迁移率的探测器材质,但收效甚微。该研究为解决薄膜晶体管迁移率这一限制平板CT机应用的核心难题提出了一种新的方案:将薄膜晶体管内的各种TFT功能外移,彻底克服薄膜晶体管迁移率对CT机的限制,使得平板探测器的读取速度变得非常快,可完美地满足CT机的扫描速度要求。这将为平板探测器应用于CT机提供了新的研究思路。

Because the mobility ratio of thin film transistors is too low,it is recognized that flat detector can not be used in CT machine.The current research direction is to find the detector material with higher mobility ratio,but with little success.This study puts forward a new scheme to solve the core problem that limits the application of CT,which is the mobility of thin film transistors:by moving various TFT functions in the thin film transistor to the peripheral circuit,the restriction of the mobility of thin film transistor on the CT machine is completely overcome,and the reading speed of the flat panel detector becomes very fast,which can perfectly meet the requirements of the scanning speed of the CT machine.This will provide new research ideas for the application of flat panel detector in CT machine.
