Abstract: A first data taking section takes first detection results from a first wireless tag reader which detects the come and go of an electronic cassette into and out of a first service zone, and also takes second detection results from a second wireless tag reader which detects the come and go of an electronic cassette into and out of a second service zone. A first alert controller drives a first speaker to start an alert when the first alert controller determines on the basis of the first detection results that the electronic cassette has gone out the first service zone. After the start of alerting, the first alert controller stops driving the first speaker to interrupt the alert when first alert controller determines that the electronic cassette has come in either the first service zone or the second service zone.

A display control unit 8e gives a three-dimensional cursor to a predetermined abnormal shadow of the plurality of abnormal shadows, and displays a stereo image using the radiographic images for left and right eyes.

Abstract: In capturing an image of a grid by an image detector, a measurement pixel that is not in the position of a specific point having a maximum or minimum value of an output signal is referred to as a first measurement pixel, and a measurement pixel that is in the position of the specific point is referred to as a second measurement pixel. The disposition of the first and second measurement pixels are determined so as to satisfy the following condition: fG/fN?odd number, wherein fG is a grid frequency and fN is a Nyquist frequency of pixels; and in shifting the grid C times by one pixel, the number of the first measurement pixels is larger than that of the second measurement pixels at any time in the range of a cycle C of a repetition pattern appearing in the image.

Abstract: 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.

Abstract: Besides normal pixels, a plurality detection pixels are arranged in an imaging surface of an FPD. In preliminary imaging, X-rays are emitted to an imaged body portion of a patient. The detection pixels receive the X-rays passed through the body portion, and output AEC detection signals. If an integral value of the AEC detection signals has reached a threshold value, X-ray emission is stopped and the preliminary imaging is completed. A main exposure condition determination unit determines a main irradiation time, being an irradiation time with the X-rays during the main imaging, based on an irradiation time with the X-rays during the preliminary imaging and the integral value of the AEC detection signals. The main imaging is performed using the main irradiation time. The normal pixels continue a charge accumulation operation over the preliminary imaging and the main imaging to produce an X-ray image for use in diagnosis.

Abstract: A console acquires a displacement amount of an X-ray source from a displacement amount detector. In the case where an electronic cassette having an image detector is not appropriately positioned with respect to a body part to be imaged, a position of the X-ray source is changed in accordance with a position of the body part to be imaged. A dose measurement field position determining unit specifies a current relative position between the X-ray source and the electronic cassette having the image detector based on a displacement amount. The dose measurement field position determining unit determines a position of a dose measurement field based on the specified current relative position.

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.
