The present disclosure relates to the use of X-ray detector cassettes that may be abutted or overlapped to form a detector assembly suitable for imaging objects that are too large to image using a single X-ray detector cassette. Such a detector assembly may be customized in terms of the size and/or shape of the field-of-view (FOV). In certain embodiments the radiation-sensitive electronics (e.g., readout electronics) are positioned to the side of the X-ray detecting components (e.g., scintillator, TFT array, and so forth), allowing the cassette to be thin relative to other detector devices and allowing the electronics to remain outside the X-ray beam path.

A radiation detector and a radiological image radiographing apparatus capable of improving the quality of an obtained radiological image without causing an additional cost are provided. A first scintillator configured to include columnar crystals generating first light corresponding to a radiation emitted through a TFT substrate is laminated on the other surface of the TFT substrate that has a first photoelectric conversion element, which has one surface from which a radiation is emitted and the other surface from which at least one of the first light and the second light is emitted and which generates electric charges corresponding to the light, and a first switching element. A second scintillator which generates second light corresponding to a radiation emitted through the first scintillator and has different energy characteristics of absorbed radiations from the first scintillator is laminated on a surface of the first scintillator not facing the TFT substrate.

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.

A computed tomography (CT) imaging system is provided. The CT imaging system includes a gantry, rotatable about an axis of rotation. The CT imaging system also includes a table configured to move a subject to be imaged into and out of a bore of the gantry. The CT imaging system further includes a radiation source mounted on the gantry and configured to emit an X-ray beam. The CT imaging system even further includes one or more detectors configured to detect the emitted X-ray beam, wherein the one or more detectors comprises a flat panel detector disposed within the table, wherein the table is configured to move the flat panel detector into and out of the bore. The CT imaging system is configured to generate a two-dimensional image of the subject utilizing the radiation source and the flat panel detector.

The present invention proposes a radiation detector including a housing, a radiation detection panel accommodated in the housing and converting radiation incident from the outside of the housing into an electric signal, a printed circuit board electrically connected to the radiation detection panel and an intermediate plate that is disposed between the radiation detection panel and the printed circuit board, supports the radiation detection panel, and is electrically connected to the ground line of the printed circuit board, wherein the intermediate plate is transmissive to the radiation.

A radiographing system includes a mobile terminal configured to store an examination time of a subject that is based on examination-related information about the subject, a radiographing apparatus configured to take a radiation image of the subject based on the examination-related information and to store an imaging time of the radiation image, and an association unit configured to associate the radiation image with the examination-related information based on the imaging time and the examination time.

An electronic cassette is provided with a sensor panel, a housing, operation buttons, a head-bottom setting section, lamps and a memory. The sensor panel has a quadrangle imaging area, and detects an X-ray image of a patient. The housing houses the sensor panel. The operation buttons are disposed on the housing. When either one of the operation buttons is pushed down, the head-bottom setting section sets either one of adjoining two sides of the imaging area to be the head of the radiographic image in the display orientation. The display section is disposed on the housing, and displays which side is set by the head-bottom setting section to be the head of the radiographic image. The memory stores head-bottom setting information and the radiographic image in association with each other.

A radiation image capturing system includes the following. An input unit is used to input that a captured radiation image is a capturing failure. A storage stores irradiating amount information regarding capturing set as the capturing failure when there is input that the captured radiation image is the capturing failure. An output unit outputs the irradiating amount information regarding the capturing set as the capturing failure stored in the storage.

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.

There can be provided an incubator (11) which relatively readily stores a cassette tray (61) in a cassette tray accommodation space (62) or takes out the cassette tray (61) from the cassette tray accommodation space (62) through one of a plurality of tray loading/unloading ports (63a-63c) even if a doctor or nurse performs an operation in a region including the outside of the cassette tray accommodation space (62) and its vicinity or even if a sophisticated article such as a sophisticated medical apparatus exists in the region including the outside of the cassette tray accommodation space (62) and its vicinity. In this incubator (11), the cassette tray accommodation space (62) includes at least two tray loading/unloading ports (63a-63c) of a front tray loading/unloading port (63a), a rear tray loading/unloading port, a left tray loading/unloading port (63b), and a right tray loading/unloading port (63c).
