    摘要: 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 (Δx/ΔFi, θ, Δθ/ΔFi, 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. This allows the parameters to be calibrated for 3D image reconstruction.

    摘要: There is provide a mobile radio apparatus capable of suppressing a mismatching loss, and increasing a transmission/reception sensitivity by means of instantly and adaptively matching the impedance between the antenna and the transmission/reception circuit whatever situation a mobile radio apparatus, such as a mobile phone or the like, may be. In a mobile radio apparatus (1), when starting control of the matching circuit (102), a control section (105) evaluates an initial chromosome stored in a storage section (106), and if there is an initial chromosome for providing an impedance matching, controls the matching circuit (102) so as to have a load value corresponding to this initial chromosome. If there is no initial chromosome for providing the impedance matching, the control section (105) evolves the initial chromosome with a genetic algorithm, derives a chromosome for providing the impedance matching, and controls the matching circuit (102) so as to have a load value corresponding to the derived chromosome.
