摘要： A radiographic imaging device includes: a radiation detector including plural pixels, each including a sensor portion and a switching element; a detection unit that detects a radiation irradiation start if an electrical signal caused by charges generated in the sensor portion satisfies a specific irradiation detection condition, and/or if an electrical signal caused by charges generated in a radiation sensor portion that is different from the sensor portion satisfies a specific irradiation detection condition; and a control unit that determines whether or not noise caused by external disturbance has occurred after the detection unit has detected the radiation irradiation start, and if the noise has occurred, that stops a current operation of the radiation detector, and causes the detection unit to perform detection.

摘要： 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.

摘要： 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.

摘要： A radiographic imaging system includes plural radiographic imaging devices that image a same subject. The radiographic imaging device includes: a radiation detector; a detection unit that detects whether or not application of the radiation has been started based on electrical signals indicating detection results of sensors that detect the application of the radiation and that are disposed in correspondence to the radiation detector; a determination unit that determines whether or not noise is superimposed on the electrical signals after the detection unit has detected whether or not the application of the radiation has been started; and a communication unit that is connected to another radiographic imaging device and transmits to and receives from the other connected radiographic imaging device a detection result signal indicating the detection result of the detection unit and a determination result signal indicating the determination result of the determination unit.

摘要： An image obtaining unit obtains a subject image, a body thickness distribution modifying unit receives input of a virtual model having an estimated body thickness distribution and modifies the estimated body thickness distribution of the virtual model to output the modified estimated body thickness distribution, and a body thickness distribution determining unit determines the outputted estimated body thickness distribution to be used as the body thickness distribution of the subject. The body thickness distribution determining unit includes a judging unit for switching, according to a judgment condition, between a first control under which the body thickness distribution modifying process is iteratively executed until a first termination condition is satisfied and a second control under which the body thickness distribution modifying process is iteratively executed until a second termination condition that is different from the first termination condition is satisfied so that the first control or the second control is executed.
