  • 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.
