20150021487 | TWO-DIMENSIONAL IMAGE DETECTING SYSTEM - When a conventional idea of determining a setting condition from a parameter of resolution (image resolution) is changed to use an X-ray tube with a stable focus size, setting conditions are determined from a focus size φ [μm] of the X-ray tube. The minimum radiography size b [μm] is settable from the focus size φ [μm] and φ≦b/2. A magnification rate ε is settable from the set minimum radiography size b [μm], a pixel pitch d [μm] of an X-ray detector, and bε/d≧5. Consequently, the minimum radiography size b [μm] and the magnification rate ε are each settable with use of the X-ray tube having the stable focus size φ [μm]. This results in stable radiography or fluoroscopy through magnifying an object in minute size. | 01-22-2015 |
20150309187 | PACKAGING FOR RETRO-REFLECTIVE MARKERS - Described is a device comprising a retro-reflective marker sphere comprising: a core ball comprising: a generally spherical body portion, a mounting base extending from one end of the body portion of the core ball, and a mounting recess having a recess opening in the mounting base and extending into the body portion of the core ball, and a retro-reflective covering on the core ball, the retro-reflective covering comprising an opening through which the mounting base of the core ball extends, wherein a flat lower surface of the mounting base is spaced proximally from a lower edge of the opening of the retro-reflective covering, and wherein the mounting recess includes an interior screw thread for engaging an exterior screw thread of a mounting post when the retro-reflective marker sphere is mounted on the mounting post. | 10-29-2015 |
20160070002 | RADIATION IMAGING APPARATUS AND RADIATION IMAGING SYSTEM - A radiation imaging apparatus for sensing a radiation image, includes a radiation imaging panel including a plurality of imaging substrates and a scintillator having a first face and a second face which oppose each other, a housing configured to house the radiation imaging panel and including a first plate-shaped portion and a second plate-shaped portion, a first support member located between the first face of the scintillator and the first plate-shaped portion of the housing so as to support the scintillator via the plurality of imaging substrates, and a second support member located between the second face of the scintillator and the second plate-shaped portion of the housing so as to support the scintillator. | 03-10-2016 |
