The radiography apparatus includes: an irradiation unit having an irradiation opening through which radiation is emitted; an image receiving unit that has an image receiving surface receiving the radiation emitted from the irradiation unit; an arm that has one end at which the irradiation unit is rotatably supported and the other end at which the image receiving unit is supported in a posture in which the irradiation opening and the image receiving surface face each other; a solenoid that locks the rotation of the irradiation unit with respect to the arm in a facing posture in which the irradiation opening and the image receiving surface face each other; and a control unit that permits the moving image capture irradiation in a state in which the rotation of the irradiation unit is locked and prohibits the moving image capture irradiation in a state in which the rotation is unlocked.

Radiography apparatus and method for controlling radiography apparatus

A radiography apparatus includes: an irradiation unit that emits radiation; an arm to which the irradiation unit and an image receiving unit that receives the radiation are capable of being attached at a position where the irradiation unit and the image receiving unit face each other with a subject interposed therebetween and which is rotated to reverse a positional relationship between the irradiation unit and the image receiving unit with respect to the subject; a first light source that is provided in the irradiation unit and emits visible light indicating an irradiation field of the radiation; and a second light source that is provided in the image receiving unit and emits visible light indicating a center position of the irradiation field of the radiation emitted by the irradiation unit.

Radiography apparatus

A radiographic image capturing apparatus includes: a radiation detector in which a plurality of pixels for accumulating electric charges corresponding to emitted radiation are arranged in a two-dimensional manner; a control unit that controls the radiation detector; a radiation emission unit that emits radiation; a changing unit that integrally changes angles of the radiation detector and the control unit with respect to a predetermined direction; a heat sink in which a guiding unit for guiding an air flow in a predetermined guiding direction is provided and which dissipates heat of the control unit; and a housing unit in which the radiation detector, the control unit, and the heat sink are housed and which has a radiation detection surface irradiated with the radiation emitted from the radiation emission unit.

Radiographic image capturing apparatus and heat diffusion method

A radiographic image capturing apparatus includes: a radiation detector in which a plurality of pixels for accumulating electric charges corresponding to emitted radiation are arranged; a control unit that controls the radiation detector; a radiation emission unit that emits radiation; a housing unit in which the radiation detector and the control unit are housed and which has a heat dissipation port and a radiation detection surface irradiated with the radiation emitted from the radiation emission unit; and a support unit that supports the radiation emission unit at a position facing the radiation detection surface and has a hollow portion forming a space continuing from an inside of the housing unit through the heat dissipation port.

Radiographic image capturing apparatus and heat dissipation method

Provided is a radiation detection cassette that can suppress an artifact resulting from scattered radiation generated within a housing and can further achieve weight reduction and improvement in corrosion resistance. The radiation detection cassette includes a radiation detector that detects radiation, and a housing that houses the radiation detector. A back housing part of the housing opposite to a radiation exposure side is formed of an alloy containing Mg and Li and containing 0.1 mass % or more of Li. A protective film is provided in a portion or all of an outer surface of the back housing part.

Radiation detection cassette

A cassette having a transmission plate disposed on radiation exposure side and transmitting radiation, and a housing part disposed on opposite to the radiation exposure side, the cassette comprises a radiation detector that is disposed between the transmission plate and the housing part, in which material of the housing part contains 5 mass % or more and 25 mass % or less of lithium.

Cassette

Provided is a method for manufacturing a housing of a radiation detection cassette that can appropriately form a recess without a housing material depositing on an end mill or the like, in a case where a recess is formed by working the housing material formed of an alloy containing Mg and Li. A method for manufacturing a housing of a radiation detection cassette that houses a radiation detector in the housing includes preparing a housing material that is formed of an alloy containing Mg and Li and contains 0.1 mass % or more of Li, forming a recess using a working method other than cutting work on a surface of the housing material, and performing cutting work on the formed recess to shape the recess.
