  • Patent number: 9408579
    Abstract: In the imaging space provided by a panoramic imaging apparatus, a phantom is arranged. The phantom is located to a predetermined tomographic plane and includes markers which image known positional information with an X-ray beam. The X-ray beam from an X-ray source is acquired as X-ray transmission data by a detector, and a panoramic image is produced using the data. Based on known positional information of the markers and information of marker positions in the panoramic image, distance information (Rs, Rd) between the X-ray tube and the detector and height information (B1) of the X-ray tube to the detector are calculated. From this calculated results and the acquired data, parameters (?x/?Fi, ?, ??/?Fi, D, A, CX, CY) defining positional relationships among the X-ray tube, the detector, and the tomographic plane are calculated such that amounts of changes in the position connecting the X-ray tube and the detector are considered in the parameters.

  • Patent number: 9351701
    Abstract: There is provided a calibration apparatus used for a photon counting type of radiation detector. In this apparatus, a radiation condition of a radiation is set such that particles of the radiation (X-rays) which are incident on a plurality of detection modules are piled up over each other at a probability which is equal to or less than a predetermined value. Under the setting of this radiation condition, detection sensitivities for the radiation are made uniform among the plurality of detection modules. Using this uniformed result, the detection sensitivities for the radiation are further made uniform every channel of each of the pixels formed by circuit groups including the plurality of detection modules, discrimination circuits and data calculation circuits and every discrimination circuit in each channel.

  • Patent number: 8891845
    Abstract: A panoramic imaging apparatus functionally includes an image processing apparatus. In this apparatus, two planar images are produced, which are subjected to registration. A registration process is applied to overall areas of two planar images based on curves decided from positions designated on the two planar images respectively. The positions on each of the planar images are aligned along a straight line, both straight lines corresponding to each other in a horizontal direction, and a scale factor for the registration is changed position by position on the straight lines. One of the two planar images is searched for a match of each local region of the other planar image, to any of regions of the one planar image, and images of the matched regions are re-produced to produce a planar image. The difference information is calculated between the planar images.
