  • Patent number: 8391581
    Abstract: An X-ray inspecting apparatus capable of high-speed inspection of a prescribed inspection area of an object of inspection is provided. The X-ray inspecting apparatus includes: a scanning X-ray source for outputting X-ray; an X-ray detector driving unit on which a plurality of X-ray detectors are mounted, and capable of driving the plurality of X-ray detectors independently; and an image acquisition control mechanism controlling acquisition of image data by X-ray detector driving unit and X-ray detectors. A scanning X-ray source emits X-ray while moving the X-ray focal point of the X-ray source to each of X-ray emission originating positions set for each X-ray detector such that the X-ray passes through a prescribed inspection area of an object of inspection and enters each X-ray detector. Image pick-up by some of the X-ray detectors and movement of other X-ray detectors to an image pick-up position are executed in parallel and alternately.

  • Patent number: 8254519
    Abstract: An X-ray inspection apparatus includes a scanning X-ray source for emitting an X-ray, an X-ray detector drive unit having a plurality of X-ray detectors mounted thereon and being capable of independently driving the plurality of X-ray detectors, and an image acquisition control mechanism for controlling the X-ray detector drive unit and acquisition of image data from the X-ray detectors. The scanning X-ray source emits an X-ray by moving an X-ray focal point position of the X-ray source to each of originating point positions of X-ray emission, which are set for the X-ray detectors such that X-rays are transmitted through a plurality of prescribed inspection areas of an inspection object and enter the X-ray detectors. Image pickup by the X-ray detector and movement of another X-ray detector are concurrently performed in an alternate manner. The image acquisition control mechanism acquires image data, and an operation unit reconstructs an image.

  • Publication number: 20110255660
    Abstract: An X-ray inspection apparatus includes an X-ray source, an X-ray detector, an X-ray detector drive unit, an image acquisition control mechanism for controlling driving of the X-ray detector by the X-ray detector drive unit and acquisition of image data from the X-ray detector, an inspection object drive mechanism for moving an inspection object, an X-ray source control mechanism, and an operation unit. The X-ray source control mechanism causes the X-ray source to output an X-ray based on an instruction from the operation unit. The image acquisition control mechanism moves the X-ray detector to a plurality of image pickup positions aligned in the Y direction based on an instruction from the operation unit. The inspection object drive mechanism moves the inspection object in the Y direction such that the X-ray detector can detect an X-ray transmitted through the inspection object at each image pickup position based on an instruction from the operation unit.

  • Patent number: 7680242
    Abstract: An X-ray examination apparatus includes a scanning X-ray source for outputting X-rays, a sensor base which is attached with a plurality of X-ray sensors and which rotates about a rotation axis, and an image acquiring control mechanism for controlling rotation angle of the sensor base and acquisition of image data from the X-ray sensors. With respect to each X-ray sensor, the scanning X-ray source moves the X-ray focal position of the X-ray source to each starting position of the X-ray emission set so that the X-ray transmits through a predetermined examination area of an examination target and enters each X-ray sensor, and emits the X-rays. The image control acquiring control mechanism acquires image data detected by the X-ray sensors, and a calculation unit reconstructs an image of the examination area based on the image data.

  • Patent number: 7522709
    Abstract: An X-ray examination apparatus changes a position of each X-ray sensor by rotating a sensor base, and resets a starting position of X-ray emission that becomes a X-ray focal position so that the X-ray enters each X-ray sensor after the position thereof is changed. A scanning X-ray source deflects an electron beam to easily change the position where the electron beam impinges a target of the X-ray source to an arbitrary location. The irradiating position of the electron beam then can be easily moved according to an accumulated irradiation time on the target. Therefore, maintenance can be performed without interrupting the X-ray examination.
