Patent ID: 8841624

Claim:
A radiographic image detector comprising: a detection section including a plurality of pixels having hexagonal shaped pixel regions arrayed in a honeycomb pattern, each pixel including, a sensor portion that generates charges according to irradiated radiation, a first switching element that reads out the generated charges, and a second switching element that reads out the generated charges; a plurality of first scan lines that are disposed one for each of respective pixel rows of the plurality of pixels along an arrayed direction of the plurality of pixels, and that are each connected to a control terminal of the first switching elements in the corresponding pixel row; a plurality of second scan lines that are disposed one for each of respective pairs of column direction adjacent pixel rows from the plurality of pixel rows, and that are each connected to a control terminal of the second switching elements in the corresponding column direction adjacent pair of pixel rows; and a plurality of data lines that are disposed to respectively intersect with the plurality of first scan lines and the plurality of second scan lines, that transmit first charge signals corresponding to charges read out by the first switching elements in the plurality of pixels in response to signals output to the plurality of first scan lines, and that transmit second charge signals corresponding to a combined charge amount of 4 mutually adjacent pixels in a column direction adjacent pair of pixel rows read out by the second switching elements of the 4 mutually adjacent pixels in response to signals output to the plurality of second scan lines, wherein the 4 pixels configure a pixel group of repeating units of 2 successive pixels along the same pixel row direction, and 2 successive pixels along the pixel row direction of a pixel column direction adjacent pixel row to the first 2 pixels, and the 4 pixels are configured by 3 pixels disposed such that two adjoining sides of each of the pixels are respectively mutually adjacent to one side of the remaining 2 pixels, and by 1 pixel disposed such that two adjoining sides are respectively mutually adjacent to one side of 2 pixels out of the 3 pixels, and wherein combinations of the 4 pixels configuring respective pixel groups in the plurality of pixel groups are determined such that, when a plurality of hexagonal shaped regions are formed adjacent to each other, the plurality of hexagonal shape regions results in a honeycomb pattern array, and wherein each of the hexagonal shape regions are formed by including inside one center of gravity of a region surrounded by an outline of the plurality of pixel groups configured by the respective 4 pixels, and by connecting together 6 individual centers of gravity present at a periphery of the one center of gravity.
