  • Method and systems for camera-aided x-ray imaging
    Patent number: 10835196
    Abstract: Various methods and systems are provided for x-ray imaging. In one embodiment, a method for an image pasting examination comprises acquiring, via an optical camera and/or depth camera, image data of a subject, controlling an x-ray source and an x-ray detector according to the image data to acquire a plurality of x-ray images of the subject, and stitching the plurality of x-ray images into a single x-ray image. In this way, optimal exposure techniques may be used for individual acquisitions in an image pasting examination such that the optimal dose is utilized, stitching quality is improved, and registration failures are avoided.
    Type: Grant
    Filed: January 24, 2019
    Date of Patent: November 17, 2020
    Assignee: General Electric Company
    Inventors: Dejun Wang, Srikrishnan V, Gireesha Rao, Katelyn Rose Nye, Nasir Ahmed Desai, Arun Kumar Chandrashekarappa, Huanzhong Li

  • Automatic estimation of anatomical extents
    Patent number: 9355454
    Abstract: A hierarchical multi-object active appearance model (AAM) framework is disclosed for processing image data, such as localizer or scout image data. In accordance with this approach, a hierarchical arrangement of models (e.g., a model pyramid) maybe employed where a global or parent model that encodes relationships across multiple co-located structures is used to obtain an initial, coarse fit. Subsequent processing by child sub-models add more detail and flexibility to the overall fit.
