  • Patent number: 10444166
    Abstract: An X-ray detection device is a device that detects X-rays having transmitted through a test subject, and comprises a filter that attenuates some of X-rays, a detector that detects the transmitted X-rays partially attenuated by the filter, a housing, and a holder that has one slit. The detector includes a line sensor, and a line sensor disposed in parallel and close to the line sensor. The holder holds the filter at a predetermined position so that the filter can cover a part of the slit, and the line sensor detects the X-rays attenuated by the filter.

  • Patent number: 10267751
    Abstract: An image acquisition device is an image acquisition device that acquires an X-ray transmission image of an object conveyed in a conveyance direction, and the image acquisition device includes an X-ray irradiator that outputs an X-ray, a belt conveyor that conveys the object in the conveyance direction, an X-ray detection camera having a scintillator that converts an X-ray penetrating the object into scintillation light, a line scan camera that detects the scintillation light and outputs a detection signal, and an amplifier that amplifies the detection signal at a predetermined set amplification factor and outputs a amplified signal, a controller that generates an X-ray transmission image based on the amplified signal, and an amplifier controller that sets one of a first amplification factor or a second amplification factor corresponding to an amplification factor lower than the first amplification factor as the set amplification factor based on a predetermined imaging condition.

  • Publication number: 20180364370
    Abstract: An X-ray detection device is a device detecting X-rays having transmitted through a test subject, and comprises a filter member including a filter that attenuates some of X-rays, a detector that detects the X-rays partially attenuated by the filter, and a housing that places the detector therein. The housing includes a principal surface including a slit capable of going through the X-rays, and a side surface including an opening which extends in the direction orthogonal to the principal surface and through which the filter can be inserted. The filter of the filter member is disposed in the housing so as to cover a line sensor of the detector and a scintillator in a state of being apart from the detector.

  • Publication number: 20180306931
    Abstract: A radiation image acquisition system includes a radiation source that outputs radiation toward an object, a scintillator that has an input surface to which the radiation output from the radiation source and transmitted through the object is input, converts the radiation input to the input surface into scintillation light, and is opaque to the scintillation light, an image capturing means that includes a lens portion focused on the input surface and configured to image the scintillation light output from the input surface and an image capturing unit configured to capture an image of the scintillation light imaged by the lens portion and outputs radiation image data of the object A, and an image generating unit that generates a radiation image of the object based on the radiation image data output from the image capturing means.

  • Publication number: 20170146930
    Abstract: A developing apparatus of the present disclosure includes a developing sleeve including a plurality of magnetic substance portions bearing, on a surface thereof, developer containing toner and carrier and conveying the developer to a developing area facing a photosensitive drum, and a magnet roller disposed within the developing sleeve and generating magnetic fluxes passing through the magnetic substance portion. The magnetic substance portion includes, on an end surface thereof, a high flux density portion disposed at least one of upstream and downstream parts in a conveyance direction of the developing sleeve and through which the magnetic fluxes pass and a low flux density portion through which the magnetic fluxes whose density is lower than the magnetic fluxes passing through the high flux density portion pass.
