A radiation imaging apparatus comprises a radiation detection unit configured to convert received radiation into an electrical signal, a communication unit configured to perform wireless communication with an external device, and an exterior at least partially formed by a non-conductive member and configured to contain the radiation detection unit and the communication unit, wherein a conductor is formed so as to cover the radiation detection unit, and the communication unit is arranged between the exterior and the conductor.

Radiation imaging apparatus

A radiographing apparatus includes a radiation detection panel that detects radiation, a casing that encloses the radiation detection panel, and a wireless power reception portion. The casing includes an entrance portion via which radiation enters, a bottom portion arranged on the opposite side of the entrance portion, and a plurality of side portions. The casing also includes a connection portion that continuously connects the bottom portion and the side portions at a position located inside a first extension plane, which is an extension of the surface of the bottom portion, and a second extension plane, which is an extension of the surface of the side portions. The wireless power reception portion is arranged at the connection portion.

Radiographing apparatus and radiographing system

A radiation imaging apparatus for supplying power in a non-contact manner includes a power reception coil disposed inside a housing together with a radiation detector and a detector contact conductive member, and configured to receive electric energy to be supplied to the radiation detector in a non-contact manner from a power feeding coil disposed outside the housing. The power reception coil is disposed in a second range including a first range in which the detector contact conductive member is formed in the normal direction (y direction) to an incident surface of the radiation detector where the radiation is incident so that an orientation of the center of a generated magnetic flux coincides with an in-plane direction (x direction) of the incident surface and coincides with a direction toward the radiation detector.

A radiographic imaging apparatus includes a sensor panel, a sound emitting member that provides notification of a state via sound, a casing that contains the sensor panel and the sound emitting member, where the casing includes a first sound transmission hole and a sound transmission member that covers the first sound transmission hole, where the sound transmission member includes a second sound transmission hole with a smaller diameter than a diameter of the first sound transmission hole. The radiographic imaging apparatus includes a detection unit that detects information related to an installed state of the radiographic imaging apparatus and a control unit that controls a volume of the emitted sound based on the detected information.

Radiographic imaging apparatus and radiographic imaging system

Provided is a radiation detecting apparatus, including: a radiation detector arranged to detect radiation; an electrical circuit board configured to control the radiation detector; a cooling unit arranged to cool the radiation detector and the electrical circuit board; and a casing arranged to accommodate the radiation detector, the electrical circuit board, and the cooling unit therein, in which at least an outer surface of the casing has a recessed portion that is recessed across a back surface portion, which is on an opposite side to a side in which the radiation enters, and a lateral surface portion adjacent to the back surface portion, and in which the recessed portion has lead-out portions formed therein, through which a wiring line removably connectable to the electrical circuit board and a piping line arranged to allow a cooling medium to flow to the cooling unit are respectively led out external to the casing.

Radiation detecting apparatus and radiation imaging system

A mobile radiation imaging apparatus includes: an irradiation unit that emits radiation; a moving unit that moves with the irradiation unit; an imaging unit that takes an image of an object irradiated with radiation and is able to transmit the image via the wireless communication or the wired communication; an obtaining unit that obtains information indicating in which area the moving unit is located among a wired communication area, a wirelessly communicable area, and a switching area for switching between the wireless communication and the wired communication; and a control unit that switches the communication with the imaging unit depending on the obtained information.

Mobile radiation imaging apparatus, method for controlling mobile radiation imaging apparatus, and storage medium

A radiation imaging apparatus includes: a first cooling fan configured to cool a first heat generation portion of a radiation detection unit housed in the radiation imaging apparatus, by blowing a cooling medium to the first heat generation portion; a second cooling fan configured to cool a second heat generation portion of the radiation detection unit housed in the radiation imaging apparatus, which is larger in amount of generated heat than the first heat generation portion, by blowing the cooling medium to the second heat generation portion; and a discharge port formed in a position nearer to the second heat generation portion than to the first heat generation portion and configured to discharge the cooling medium which received heat from the first heat generation portion and the cooling medium which received heat from the second heat generation portion.

An X-ray imaging apparatus includes an imaging unit which is rotatable relative to a platform about a shaft portion perpendicular to an X-ray detecting surface, so as to change the orientation relative to a subject.

X-ray imaging apparatus

A radiation imaging apparatus includes a radiation detector that captures an image of a subject by detecting radiation transmitted through the subject and converting the radiation into an image signal; an electrical component processes the image signal; an interior housing accommodates the radiation detector and the electrical component therein; an exterior member surrounds the interior housing; an air circulating unit is disposed in the interior housing so as to circulate air inside the interior housing; and a cooling unit is disposed inside of the exterior member and outside of the interior housing so as to cool the interior housing.

A coupler is provided with a protrusion and a flange-shaped locking portion. A case of an image receptor houses an X-ray detector and an unlocking mechanism including a movable locking portion. The movable locking portion is made to protrude into a depression by the urging force of a locking assist spring. When the case is attached to the coupler, the movable locking portion locks the locking portion, thereby holding the case and the coupler together. The central axis of the cylindrical surface of the depression corresponds to substantially the center of the X-ray detection area of the X-ray detector.

X-ray radiographing apparatus

An X-ray imaging apparatus includes an X-ray tube, an X-ray generation control unit configured to control the X-ray tube with a controller and a power supply, and a holding unit configured to hold the X-ray tube. The holding unit includes two support legs to be spread at an arbitrary angle, and a connecting portion configured to turnably connect upper ends of the support legs. The holding unit holds the X-ray tube near the connecting portion.

A radiation imaging apparatus that performs radiation imaging of a breast of a subject, which includes a table for laying down the subject; a receiving section that receives a breast of the subject laid on the table in a supine position; a radiation imaging section including a radiation emission unit and a radiation detection unit each located at a position opposing to each other being interposed by the breast of the subject received in the receiving section; and a drive unit that shifts the receiving section to a position suitable for imaging the breast of the subject.

A cover is elastically supported on a frame by elastic members. Engaging members are provided between the frame and the cover, and the cover is fixed to the frame by the engaging members as necessary. In the first state in which the movement of the cover is not restricted, the cover is movable with respect to the frame. In the second state, the cover is engaged with the frame and is fixed.
