Out of a group of measurement pixels based on which an average value of dose measurement signals is calculated, a [C/D] number of measurement pixels are disposed or chosen in a cycle Z=(R×C)±D.

R represents a natural number of 0 or more. D represents an integer less than the cycle C. [C/D] represents a maximum integer equal to or less than C/D. Provided that at least the [C/D] number of measurement pixels are shifted C occasions by one pixel, if D=1, the average value of the dose measurement signals is invariable without any variations.

The irradiation field determination unit determines an irradiation field of an imaging surface of an FPD. The object area determination unit determines an object area from a comparison result between a first expected received dose of a directly exposed area and dose detection signals of detection pixels situated in the irradiation field. The measurement area determination unit determines a measurement area, which corresponds to a region of interest, from a comparison result between a second expected received dose of the measurement area and the dose detection signals of the detection pixels situated in the irradiation area and the object area. The dose detection signals of the detection pixels situated in the measurement area are used for AEC.

Abstract: In a radiographic imaging apparatus, a radiation image of an object is detected by use of one of first and second electronic cassettes, to input the radiation image to the console device. The first electronic cassette is changed over between a normal transmission mode and a relay transmission mode. In the normal transmission mode, the radiation image is transmitted through a path from the first electronic cassette to the console device, and in the relay transmission mode, the radiation image is transmitted from the first electronic cassette to the second electronic cassette wirelessly and then from the second electronic cassette to the console device. Transmission of a radiation image can be performed reliably without unwanted interruption, because an indirect path of the relay transmission mode can be used even upon occurrence of a technical problem of inefficiency in the normal transmission mode.

Abstract: A radiation image capture device includes plural radiation detection panels that each detect incident radiation that has passed through an imaging subject, that each generate a radiation image, and that are disposed in a row in a direction orthogonal to the radiation incident direction. The radiation image capture device designates a display target image from out of plural radiation images respectively generated by the plural radiation detection panels, and transmits the designated display target image to a console. At least a radiation image other than the display target image is stored in an image memory. The console displays on a display section the received display target image and, in response to data indicating a display request for a radiation image other than the display target image, also displays on the display section the radiation image other than the display target image read from the image memory.

Abstract: In a detection panel, plural pixels which receive X-ray and accumulate electric charge and plural measuring pixels which detect X-ray dose are provided on an imaging surface. The plural measuring pixels are arranged periodically with an interval. In a position facing to the imaging surface, there is a grid where X-ray absorbing sections and X-ray transmitting sections are arranged in a periodic alternating manner in a first direction. Since the arrangement period of the measuring pixels in the first direction is different from a fluctuation period of grid detection signals obtained when the grid is photographed by the detection panel, output values of the plurality of measuring pixels disperse and a fluctuation range of average values is suppressed.

Abstract: A detection panel has a plurality of pixels for accumulating electric charge by receiving X-rays, and a plurality of detection pixels for detecting an X-ray dose in an imaging surface. The detection pixels are disposed periodically with leaving space. A grid, which has X-ray absorbing portions and X-ray transmitting portions alternately and periodically arranged in a first direction, is disposed in a position opposed to the imaging surface. Since an arrangement period of the detection pixels in the first direction is different from an arrangement period of the X-ray absorbing portions, an output value of each detection pixel is distributed and hence the average of the output values has a reduced variation range.
