Abstract
According to the present invention, a photoelectric converter comprises a plurality of substrates, which are located adjacent to each other and on which a plurality of photoelectric conversion devices are two-dimensionally arranged, either scan circuits or detection circuits, at least, that are arranged on two opposing sides of the photoelectric converter, whereby scanning directions either from the scan circuits or from the detection circuits, which are arranged on the two opposing sides, are capable of being set so as to be performed in like directions.
Claims18
A photoelectric converter comprising:
- a scan circuit for scanning an array of photoelectric conversion devices arranged two-dimensionally;
- and
- a detection circuit for detecting a signal outputted from said array of photoelectric conversion devices,
- wherein said scan circuit comprises a plurality of IC chips capable of scanning bi-directionally, said IC chips having the same circuit structure, respectively, and being disposed on opposing two sides of said array of photoelectric conversion devices arranged two-dimensionally,
- wherein a scanning direction of said bi-directional scanning for the two sides is determined according to one or more common input signals, and
- wherein each IC chip receives as input, one of said one or more common input signals that determine the scanning direction.
An X-ray image pick-up device comprising:
- a scan circuit for scanning a conversion device array receiving an X-ray image and generating an electric signal corresponding to the X-ray image;
- and
- a detection circuit for detecting the signal outputted from said conversion device array,
- wherein said scan circuit comprises a plurality of IC chips capable of scanning bi-directionally, said IC chips having the same circuit structure respectively, and being disposed on opposing two sides of said conversion device array,
- wherein a scanning direction of said bi-directional scanning for the two sides is determined according to one or more common input signals, and
- wherein each IC chip receives as input, one of said one or more common input signals that determine the scanning direction.
