A radiographic image capturing apparatus includes: a two-dimensional array of radiation detecting elements that generate one or more electric charges in proportion to a dose of incident radiation; and a control unit that performs control, at least, to read the electric charges from the radiation detecting elements and generate image data. An image capturing mode is switchable between a controlled mode in which the radiographic image capturing apparatus is under control of an external console and a stand-alone mode in which the radiographic image capturing apparatus autonomously performs image capturing without the control of the console. When the image capturing mode is switched to the controlled mode or the stand-alone mode, the control unit changes its own process so as to meet the switched image capturing mode.

A radiographing apparatus includes a radiation detection panel including an effective image-acquisition area configured to detect radiation and a casing configured to house the radiation detection panel. The casing includes an incidence surface on which the radiation is incident, a back surface opposite the incidence surface, and a side surface between the incidence surface and the back surface. On the side surface of the casing, a level-difference portion indicating a position based on the effective image-acquisition area and a protrusion protruding more outward than the level-difference portion are provided.

A radiation imaging system includes: multiple radiation imaging apparatuses each including a radiation detecting panel and an enclosure enveloping the radiation detecting panel. The multiple radiation imaging apparatuses are arrayed so that a part of each of the radiation imaging apparatuses spatially overlap as seen from a radiation irradiation side, and a radiation image is acquired based on image signals from each of the multiple radiation imaging apparatuses. The enclosure of at least one radiation imaging apparatus of the multiple radiation imaging apparatuses is formed so that a radiation transmittance of the enclosure which defines the overlapping region is higher than a radiation transmittance of the enclosure which defines a different region.

An X-ray detector holder stand maintaining the position of a detector is proposed. A pillar erected on a base has a sliding window formed on the front surface of a pillar housing to extend upwards/downwards. A rack is fixed inside the pillar housing to extend perpendicularly. A wire is wound around multiple pulleys to extend perpendicularly to the front/rear side of the rack. A balance weight is coupled to the wire behind the rack inside the pillar housing. An arm includes a sliding block guided along the sliding window, a stopper gear coupled to the sliding block to rotate between a locking position and an unlocking position, an elastic pressurizing means for pressurizing the stopper gear to rotate to the locking position, and a lever means for rotating/operating the stopper gear to the unlocking position. A holder is coupled to an end portion of the arm to enable rotational manipulation.

A radiographic image capturing system includes the following. A radiographic image capturing apparatus includes a two-dimensional array of radiation detecting elements and a control circuit which controls reading of image data from each of the radiation detecting elements based on a predetermined capturing sequence. An image processor has first gain data to correct gains of the radiation detecting elements, and generates a radiographic image based on the corrected image data. The control circuit of the radiographic image capturing apparatus is capable of varying at least one of a reverse bias voltage and a signal line voltage to be applied to the corresponding signal line. The control circuit reads a signal value from each of the radiation detecting elements, creates second gain data based on the read signal value, and corrects the radiographic image with the first gain data and the second gain data.

A digital radiography detector has a two dimensional array of photosensors, with control electronics electrically connected to the photosensors. A substantially rigid housing encloses the photosensors and the control electronics. A surface of the housing includes antimicrobial material to inhibit growth of pathogens.

A radiation image capturing system including: a radiation image capturing apparatus which is portable and reads emitted radiation as image data; and a plurality of consoles, wherein when the radiation image capturing apparatus is attached to an attachment section which is associated with one console among the plurality of consoles, the one console determines whether the radiation image capturing apparatus is registrable, and when the one console determines that the radiation image capturing apparatus is registrable, the one console registers the radiation image capturing apparatus, and in a case where the radiation image capturing apparatus is already registered in another console among the plurality of consoles, the another console cancels registration of the radiation image capturing apparatus only when the one console registers the radiation image capturing apparatus.

A radiographic capturing apparatus includes the following. A wireless communication circuit or a wireless communication device establishes wireless communication with an external unit. A power supply circuit feeds electrical power to the wireless communication circuit or the wireless communication device and is switchable between a low-load mode and a high-load mode. The power supply circuit is able to feed a current having a larger value in the high-load mode than in the low-load mode. A power supply efficiency of the power supply circuit in the high-load mode is lower than that in the low-load mode when a current having a small value as in the low-load mode is fed in the high-load mode. A switcher switches a load mode of the power supply circuit based on the detected or obtained load state. A built-in power supply feeds electrical power to the power supply circuit.

A radiographic image capturing apparatus, includes the following. A sensor panel includes scanning lines, signal lines, a two-dimensional array of radiation detecting elements each having a first electrode and a second electrode, bias lines each applying a reverse bias voltage to the corresponding radiation detecting element, and switching elements. The first electrode of each radiation detecting element is connected to the corresponding bias line. The second electrode of the radiation detecting element is connected to the corresponding signal line via the corresponding switch element. A determination unit determines any defect in the sensor panel based on a signal value read after varying a potential difference between each signal line and the corresponding bias line or a signal value read after turning-on or turning-off of each switching element during a readout operation from the corresponding radiation detecting element.

A digital radiographic detector having a radiolucent cover and housing at one or more edges of the detector allows radiographic imaging using multiple detector arrangements with overlapping edges that do not obstruct radiographic images captured thereby.
