摘要： A radiation detector includes control lines extending in a first direction, data lines extending in a second direction orthogonal to the first direction, photoelectric conversion parts respectively in regions defined by the control and data lines, noise detecting parts arranged outside a region where the photoelectric conversion parts are located, and a scintillator located on the region where the photoelectric conversion parts are located.
Each photoelectric conversion part includes a first thin film transistor electrically connected to corresponding control and data lines, and a photoelectric conversion element including an electrode electrically connected with the first thin film transistor.
Each noise detecting part includes a second thin film transistor electrically connected to corresponding control and data lines, and a capacitance part electrically connected with the second thin film transistor.
The capacitance part length is less than the electrode length in at least one of the first or second direction.-

摘要： A radiation detector includes control and data lines extending respectively in mutually-orthogonal first and second directions, photoelectric conversion parts respectively in regions defined by the control and data lines, noise detecting parts outside a region including the photoelectric conversion parts, a control circuit inputting control signals to first and second thin film transistors located respectively in the photoelectric conversion and noise detecting parts, a signal detection circuit reading image data and noise signals respectively from the photoelectric conversion and noise detecting parts, and an image configuration circuit configuring a radiation image based on the signals that are read. The signals from the photoelectric conversion parts adjacent to the noise detecting parts are not read and/or are not used by the image configuration circuit when configuring the radiation image, and/or the photoelectric conversion parts adjacent to the noise detecting parts are not electrically connected with the control and/or signal detection circuits.
