放射线检测器
摘要：
本发明提供能高精度地检测放射线的入射开始时刻的放射线检测器。实施方式的放射线检测器包括：基板；设置在所述基板上并向第一方向延伸的多条控制线；设置在所述基板上并向与所述第一方向相交的第二方向延伸的多条数据线；具有与对应的所述控制线以及对应的所述数据线电连接的薄膜晶体管、并直接地或与闪烁体协同地检测放射线的多个检测部；对所述薄膜晶体管的导通状态和截止状态进行切换的控制电路；在所述薄膜晶体管处于导通状态时读取图像数据的信号检测电路；以及基于所述薄膜晶体管处于导通状态时读取到的图像数据的值来判定所述放射线的入射开始时刻的入射放射线检测部。
摘要（英）：

A radiation detector includes a substrate, control lines provided on the substrate and extending in a first direction, data lines provided on the substrate and extending in a second direction crossing the first direction, and detection parts arranged in a matrix. Each detection part includes a thin film transistor and a conversion part converting radiation or light into electricity. Further, a control circuit switches an on state and an off state of each thin film transistor and a signal detection circuit reads out image data in the on state of the thin film transistor. Further, the detector judges a start time of radiation incidence based on a value of the image data read out in the on state of each thin film transistor.
