摘要： A radiation imaging apparatus includes a pixel array including pixels for detecting radiation and column signal lines, a detector for detecting signals that appear in the column signal lines, and a controller. Each pixel includes a conversion element for converting radiation into an electrical signal and a switch for connecting the conversion element and a column signal line. In a state in which the switches of the pixels irradiated with radiation are open, the detector detects, as a radiation signal, a signal appearing in at least one column signal line. The controller converts an integrated value of the radiation signal into an integrated irradiation amount of radiation. The controller determines, based on the radiation signal and a signal read out by the detector from at least one pixel in a state in which the switch of the at least one pixel of the pixels is closed, a conversion coefficient to convert the integrated value into the integrated irradiation amount.

摘要： An FPD detects an X-ray image of an object. The FPD includes a plurality of pixels arranged in its image capturing field. Each pixel receives X-rays emitted from an X-ray source, and outputs a pixel value in accordance with an X-ray dose applied thereto. A pixel determiner determines a minimum-value pixel out of the pixels based on the pixel values of the pixels. The minimum-value pixel is a pixel whose pixel value is the lowest. The pixel determiner sets the minimum-value pixel as an exposure control pixel. A comparator compares a first integrated value, which is an integrated value of the pixel values of the minimum-value pixel, with a predetermined first threshold value. The comparator performs X-ray emission control such that, when the first integrated value has reached the first threshold value, the X-ray source stops emitting the X-rays.

摘要： An image detector is disposed behind a grid. The image detector has normal pixels and measurement pixels. 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. Wherein, C represents a cycle of a repetition pattern appearing in an arrangement direction of X-ray transparent layers and X-ray absorbing layers in an X-ray image of the grid, and is represented in units of the number of pixels. 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.
