  • Patent number: 10914845
    Abstract: 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.

  • Publication number: 20150366524
    Abstract: A radiographic apparatus includes a radiation sensor panel and a housing that encloses the panel. The radiation sensor panel has a detection surface on which a converting element that detects radiation or light is disposed. The housing includes an incident, a slope, and a flat surface portion. Radiation enters the radiographic apparatus through the incident portion, which is located adjacent to the detection surface. The slope portion is located at a housing end portion and on a radiation sensor panel side opposite to the detection surface. The slope portion is inclined with respect to a direction of a housing thickness. The flat surface portion is located on the side of the radiation sensor panel opposite to the detection surface and is substantially parallel to a flat portion of the incident portion. The slope portion has an average thickness that is greater than an average thickness of the flat surface portion.

  • Publication number: 20140177804
    Abstract: An X-ray imaging apparatus includes a plurality of X-ray detection cassettes, and an information processing section configured to communicate with the plurality of X-ray detection cassettes and to process information concerning the plurality of X-ray detection cassettes. Each of the plurality of X-ray detection cassettes transmits/receives, to/from the information processing section, first information that corresponds to an image control signal and image data of the X-ray detection cassette and second information that is different from the first information. In a case where a time at which the first information is transmitted/received and a time at which the second information is transmitted/received coincide with each other, the first information is preferentially transmitted/received.
