US Patent 7138637 X-ray imager

In a case where X-ray imaging is carried out by using a scintillator (4), a plurality of CCD chips to be driven by means of TDI are arranged, and a horizontal charge compressing vertical shift register row (2c) that is narrow in width is interposed between an imaging region (2vv) and a horizontal shift register (2h), whereby a space is created near the charge transfer direction terminal of the horizontal shift register (2h). By providing an amplifier (7) in this space, an increase in space of the device with respect to the imaging region can be prevented.
