  • Method and systems for correcting x-ray detector tilt in x-ray imaging
    Patent number: 11172908
    Abstract: Various methods and systems are provided for x-ray imaging. In one embodiment, a method comprises acquiring, with an x-ray detector tilted at an angle with respect to an x-ray source, an x-ray image, calculating the angle from the x-ray image, generating a corrected x-ray image based on the calculated angle, and displaying the corrected x-ray image. In this way, tilt artifacts caused by the x-ray detector being tilted with respect to the x-ray source may be removed from an x-ray image.
    Type: Grant

  • Systems and methods for image correction in an X-ray device
    Patent number: 10531845
    Abstract: A method for image correction in a mobile X-ray device includes obtaining an X-ray image corresponding to a region of interest, where the X-ray image includes a projection of the region of interest by an X-ray beam on a detector plane. The method further includes receiving a tilt parameter corresponding to the detector plane. Moreover, the method includes generating a corrected X-ray image based on the X-ray image and the tilt parameter using a perspective projection technique, where the corrected X-ray image corresponds to a projection of the region of interest on a corrected detector plane.
