  • Hybrid flat panel detector for cone beam CT systems
    Patent number: 11723612
    Abstract: The present invention relates generally to X-ray detectors and more particularly to a system and a method for integrating an anti-scattering grid with scintillators to significantly enhance the performance of flat panel X-ray detector. In particular, the performance of a flat panel X-ray detector may be enhanced by photon counting detector pixels configured underneath the septa of a 2D antiscatter grid.
    Type: Grant

  • Scanner Utilizing Beam Computed Tomography And Antiscatter Grid
    Publication number: 20230225685
    Abstract: A portable computed tomography (CT) system includes an O-shaped gantry defining an opening, an x-ray source operably coupled to the O-shaped gantry, and a flat panel detector (FPD) coupled to the O-shaped gantry and having a two-dimensional anti-scatter grid (2D ASG) coupled to a side of the FPD facing the opening. With the O-shaped gantry having the FPD, the object may be imaged in a first field of view (FOV) with the detector arranged in a centered geometry. Then, the detector may be arranged in an offset geometry, through-holes of the ASG may be aligned with x-ray emission paths of the x-ray source, and the object may be imaged in a second FOV with the detector arranged in the offset geometry.
