摘要： There is provided a panoramic imaging apparatus which serves as a radiation imaging apparatus. The panoramic imaging apparatus includes an X-ray tube radiating an X-ray as a radiation, a detector outputting digital-quantity frame data corresponding to an incident X-ray, and moving means moving the pair of X-ray tube and the detector relatively to an object. The apparatus further includes means for acquiring the frame data from the detector during movement of the X-ray tube and the detector, and means for optimally focusing a portion being imaged of the object using the acquired data and producing a three-dimensional optimally focused image in which the real size and shape of the portion being imaged are reflected.

摘要： A human body back-scattering inspection system is disclosed. The system comprises a flying-spot forming unit configured to output beams of X-rays, a plurality of discrete detectors which are arranged vertically along a human body to be inspected, and a controlling unit coupled to the flying-spot forming unit and the plurality of detectors, and configured to generate a control signal to control the flying-spot forming unit and the plurality of detectors to perform a partition synchronous scan on the human body to be inspected vertically. The present disclosure utilizes the geometry property of the human body back-scattering inspection system, and proposes a multiple-point synchronous scan mechanism which largely accelerates the inspection of human body.

摘要： An X-ray imaging apparatus includes an X-ray source including a plurality of X-ray focuses, an X-ray detector which detects X-rays emitted from the X-ray focuses and transmitted through an object, and a control unit which controls the X-ray source and the X-ray detector. The X-ray imaging apparatus selects a pair of X-ray focuses, of X-ray focuses of the plurality of X-ray focuses which project images on the X-ray detector through a region of interest which is an imaging region of the object, from which emitted X-rays define an intersecting angle coinciding with a predetermined angle in the region of interest, and decides an X-ray focus to be used for imaging from X-ray focuses between the selected pair of X-ray focuses. An X-ray image is captured by emitting X-rays from the decided X-ray focus and causing the X-ray detector to detect the X-rays.
