Abstract
The present invention provides a radiographic image detector that may maintain even resolution in 6 directions before and after 3-pixel binning process or 4-pixel binning process. A radiation detector is disposed with plural pixels that have hexagonal shaped pixel regions, arrayed in a honeycomb pattern. Scan lines connected to TFT switches in each of the pixels are disposed one for each of the pixel rows. Grouped scan lines are also disposed one for each of the pixel rows for reading and combining 3 pixels or 4 pixels worth of charges at the same timing for plural pixel groups, each configured from 3 pixels or 4 pixels in a radiation detection element. ON signals are simultaneously sent by the grouped scanned lines to the TFT switches to perform 3-pixel binning or 4-pixel binning.
