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: A measurement area selection circuit has an irradiation field determination unit, an object area determination unit, and a measurement area determination unit. 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 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.

Abstract: Upon input of a synchronization signal, which indicates a start of an X-ray emission, from a source control unit for controlling an X-ray source, an electronic cassette makes an FPD start an accumulation operation and measurement of an X-ray dose. The electronic cassette and a console command their communicators to stop communication of any signal other than a stop signal, which stops the X-ray emission from the X-ray source, during the accumulation operation of the FPD. As soon as the X-ray dose has reached a predetermined threshold value, the electronic cassette transmits the stop signal to the source control unit through the console. A delay in transmission of the stop signal due to communication congestion or signal collision does not occur, because the electronic cassette and the console stop the communication of the signal other than the stop signal.

Abstract: A source controller unit for controlling an x-ray source is provided with a detection signal interface for receiving detection signals from detective pixels of an electronic cassette or an integrated value of the detection signals only, or an interface for receiving a radiation stopping signal only. The source controller unit receives other radiation signals than the radiation stopping signal, such as a radiation admitting signal, through a radiation signal interface. The source controller unit uses the detection signals, the integrated value thereof, or the radiation stopping signal as exposure control signals for stopping radiation from the x-ray source. Since the exposure control signals are received on the specific interface therefor, the source controller unit does not need signal sorting operation nor receive different kinds of signals at the same time, improving the speed of radiation stopping procedure.

Abstract: There are provided a medical assistance device, an operation method of a medical assistance device, a non-transitory computer-readable recording medium, and a medical assistance system capable of improving work efficiency by reducing the burden on a user. When a request receiving unit has not received an input of a designated data range or when there is a difference between the designated data range and a first recommended data range, an automatic data range setting unit reads a second recommended data range of the latest event from a second recommended data range list. The medical data acquisition unit extracts medical data corresponding to the second recommended data range from the medical data in the entire course of treatment for the patient. The program control unit executes a diagnostic assistance program by giving medical data corresponding to the second recommended data range as input data, and outputs diagnostic assistance information.
