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.

A scattered radiation removal unit removes a scattered component from the radiographic image using at least imaging conditions. A correction information acquisition unit acquires correction information for correcting the degree of removal of the scattered component and changes the imaging conditions on the basis of the correction information. The scattered radiation removal unit performs a process of removing the scattered component from the radiographic image on the basis of the changed imaging conditions.

Abstract: An AEC unit of an electronic cassette sets a dose target value and a short-circuited pixel used for AEC based on a radiographing condition. When a control unit of the electronic cassette detects start of irradiation of X rays, the AEC unit starts integration of a cumulative dose of X rays which are incident to a target region based on a dose detection signal output by the short-circuited pixel. The AEC unit predicts a stop timing at the time point t1, waits until the time point t2 which is a predetermined time earlier than a scheduled stop time, and sends a stop timing notification to an X-ray generation device at the time point t2. When the stop timing notification is received, a X-ray source control device immediately inputs an irradiation stop command so as to stop an operation of an X-ray source.

Abstract: The present invention provides a radiographic imaging system, a radiographic imaging device, a handheld terminal device and a radiographic imaging method that may improve convenience for a user, in a case in which handheld terminal device is used for radiographic imaging. In a case where a radiographic image is imaged without using a console, the radiographic imaging device generates an image ID and transmits to the handheld terminal device. The handheld terminal device associates the received image ID with a patient ID and memorizes in a memory section. Meanwhile, the radiographic imaging device associates image data of the imaged radiographic image with the image ID and memorizes in a memory section. After imaging is completed, the console separately receives the associated image ID and patient ID from the handheld terminal device and receives the associated image ID and image data from the radiographic imaging device.

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.

Abstract: A cassette holder of an imaging stand is provided with first and second catch members for catching and holding an electronic cassette from above and below. The first catch member has a multi connector connected to a multi terminal of the electronic cassette. The multi connector is offset with respect to a center line of an imaging surface of the cassette holder. The multi terminal is offset with respect to a center line of an irradiation surface of the electronic cassette in the same direction by the same amount as those of the multi connector. In a state where said electronic cassette mounted on a tray is loaded into the cassette holder, the center line of the irradiation surface coincides with the center line of the imaging surface.
