Abstract: The current disclosure provides methods and systems for rapidly and consistently determining medical image quality metrics following acquisition of a diagnostic medical image. In one embodiment, the current disclosure teaches a method for determining an image quality metric by, acquiring a medical image of an anatomical region, mapping the medical image to a positional attribute of an anatomical feature using a trained deep neural network, determining an image quality metric based on the positional attribute of the anatomical feature, determining if the image quality metric satisfies an image quality criterion, and displaying the medical image, the image quality metric, and a status of the image quality criterion via a display device. In this way, a diagnostic scanning procedure may be expedited by providing technicians with real-time insight into quantitative image quality metrics.

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.

Abstract: A mobile X-ray system for digital tomography is disclosed. The mobile X-ray system comprising a multiple degree of freedom robotic arm comprising one or more extendable arms and a column member; an X-ray source mounted on an extendable arm of the one or more extendable arms; an X-ray detector; and a control unit coupled to the robotic arm, the X-ray source and the X-ray detector, wherein the control unit is configured to control the movement of the extendable arm and the column member for moving the X-ray source along a path to perform tomography imaging of a subject.

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.
