    摘要: First and second grids are arranged between an X-ray source and an X-ray image detector. The first and second grids have the similar configuration except for width, pitch, and thickness of X-ray absorbing sections. The first grid is composed of subdivision grids arranged with substantially no space between each other on a flat surface of a substrate made of glass, for example. Each subdivision grid has a shape of a regular hexagon. Each subdivision grid has the X-ray absorbing sections and X-ray transmitting sections extending in Y direction and arranged alternately in X direction. The X-ray absorbing sections of the adjacent subdivision grids are aligned substantially parallel to each other. The X-ray transmitting sections of the adjacent subdivision grids are aligned substantially parallel to each other. No side of the subdivision grid is parallel to an extending direction of the X-ray absorbing sections and the X-ray transmitting sections.

    摘要: In a radiographic apparatus, positions of a radiation grid and a radiation detector are determined such that, when a radiation source and the radiation detector are in a standard position, an arrangement pitch of shadows of absorbing foil strips appearing on a detecting plane of the radiation detector as a result of a radiation beam being emitted from the radiation source and blocked by the radiation grid is an integral multiple of an arrangement pitch in a transverse direction of radiation detecting elements. Further, the shadows of the absorbing foil strips appear without covering transversely adjacent pairs of the detecting elements.

    摘要: When generating a 3D image of a subject or patient, a cone beam X-ray source (20a, 20b) is mounted to a rotatable gantry (14) opposite an offset flat panel X-ray detector (22a, 22b). A wedge-shaped attenuation filter (24a, 24b) of suitable material (e.g., aluminum or the like) is adjustably positioned in the cone beam to selectively attenuate the beam as a function of the shape, size, and density of a volume of interest (18) through which X-rays pass in order to maintain X-ray intensity or gain at a relatively constant level within a range of acceptable levels.

    摘要: A composite material is constituted by fine nano-oxide particles, a dispersant, and a transparent resin material. The dispersant includes a polymer of vinyl monomer having a binding acidic group. When φ is a dimensionless number defined by an average particle size (nm) of the fine nano-oxide particles divided by nm, the polymer has a degree of polymerization of an integer of 3 or more and 8×φ or less with the proviso that the integer is a numerical value obtained by dropping a decimal fraction. The composite material is produced through a step of obtaining a dispersant comprising a polymer by polymerizing a vinyl monomer having a binding acidic group in the presence of polyamine or in an aqueous dilute dispersion, and a step of mixing the dispersant, fine nano-oxide particles, and a transparent resin material.

    摘要: Methods and apparatus for generating an x-ray image. An object is interposed between a detector and an x-ray source. A grid is interposed between the x-ray source and the object. The grid is exposed to primary x-ray energy generated by the x-ray source, thereby exposing the object to a first portion of the primary energy via the interstices of the grid. A second portion of the primary energy is received with first areas of the detector corresponding to the interstices of the grid. Secondary x-ray energy is received with the first areas of the detector and with second areas of the detector corresponding to the elements of the grid. The secondary energy results from scattering of the primary x-ray energy. Image data are generated by altering data from the first areas with reference to data from the second areas.
