  • Publication number: 20150305696
    Abstract: An X-ray tomographic imaging apparatus includes an X-ray and a direct conversion type of detector. The X-ray tube and the detector are supported by the support means so as to be rotatable along curved orbits mutually independently. Under instructions from a computer, scans and image reconstruction are performed. The X-ray tube and the detector are moved along the orbits mutually independently so that X-ray beams are always transmitted through a desired tomographic plane of an object at desired angles. Acquired frame data are used to produce a panoramic image of the plane, while the frame data and the panoramic image are used to produce a tomographic image in which structural components of the object are optically focused and distortions caused due to differences in X-ray paths are suppressed. The apparatus can be used as devices for dental, medical diagnosis and nondestructive inspection, and can have a CT imaging function.

  • Publication number: 20140091228
    Abstract: A radiation detecting apparatus includes a radiation detector, a power source, a current detector, and a bias voltage adjuster. The detector includes a semiconductor layer having a compound semiconductor directly converting incoming radiation photons to electric charges and a pair of electrode layers stacked individually on both surfaces of the semiconductor layer. One layer of the paired electrode layers has plural collecting electrodes which enable the semiconductor layer to have one-dimensionally or two-dimensionally arrayed pixels. The power source applies a direct-current bias voltage between the electrodes such that the electric charge is collected to one electrode of the electrodes. The current detector detects current supplied from the power source when the power source applies the bias voltage between the electrodes. The bias voltage adjuster changes a value of the bias voltage applied by the power source depending on a value of the current detected by the current detector.

  • Publication number: 20130114799
    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.
