20130161525 | RADIOGRAPHIC IMAGE DETECTOR, RADIOGRAPHIC IMAGING APPARATUS, RADIOGRAPHIC IMAGING SYSTEM - The present invention provides a radiographic image detector that may maintain even resolution in 6 directions before and after 3-pixel binning process. Namely, out of plural pixels with hexagonal shaped pixel regions in a radiation detector, for plural pixel groups respectively configured from 3 pixels, 3 pixels worth of charges in the radiation detector are read together, the charge signals of these 3 pixels combined, and integrated in sequence with a charge amplifier. For specific pixel groups, out of 3 pixels configuring the specific pixel groups, the charge signals of 2 pixels worth, and the charge signal of the remaining 1 pixel worth are summed with the same charge amplifier using shifted integration timings. 3-pixel binning is thereby performed. | 06-27-2013 |
