Patent number: 10310106Abstract: A dual/multi-energy x-ray image sensor with stacked two-dimensional pixel arrays. Each pixel in one pixel array has a corresponding “overlaid” pixel in the other pixel array. The pixel arrays are stacked parallel and aligned so that they are nominally normal to the x-ray path, and so that a straight path taken by an x-ray photon from the x-ray source to a pixel in one pixel array will also nominally intersect the corresponding pixel in the other pixel array(s). The energy image sensor provides an x-ray scanning detector system, which has increased signal levels and signal-to-noise ratios over dual- or multi-energy detectors using linear diode arrays, specifically when the pixel arrays are TDI pixel arrays that offer higher sensitivities in high-speed line-scan applications. Signal processing circuitry is placed on a periphery of the pixel arrays and shielded. Dual-to-multiple energy applications can be accomplished by increasing the number of stacked pixel arrays.Type: GrantFiled: October 24, 2016Date of Patent: June 4, 2019Assignee: X-Scan Imaging CorporationInventors: Shizu Li, Linbo Yang, Nguyen Phuoc Luu, Chinlee Wang, Hsin-Fu Tseng

Patent number: 7449709Abstract: A cassette is delivered from a cassette loader through a stock unit to a releasing unit. After a stimulable phosphor panel is supplied from the cassette to a reading unit by an unlocking mechanism and a panel ejecting mechanism, the cassette is fed to a position below an erasing unit so as to wait for the stimulable phosphor panel. After recorded radiation image information is read from the stimulable phosphor panel by the reading unit, the stimulable phosphor panel is fed to the erasing unit, which erases remaining radiation image information from the stimulable phosphor panel. Thereafter, the stimulable phosphor panel is stored back into the waiting cassette, which is delivered to a cassette discharger.Type: GrantFiled: September 16, 2005Date of Patent: November 11, 2008Assignee: FUJIFILM CorporationInventors: Yuzuru Ohtsuka, Masakazu Nakajo, Osamu Kuroda, Yoshihiro Ishikawa, Hideki Suzuki, Yasunori Ohta
