  • 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.

  • Patent number: 10799206
    Abstract: A method of calibrating a system for imaging a subject is provided. The method includes determining a position of an X-ray source of the system operative to transmit X-rays through the subject; and calibrating the position of the X-ray source with respect to a detector of the system, based at least in part on a field of view of the X-ray source, the detector operative to receive the X-rays transmitted by the X-ray source. In embodiments, the method includes positioning an X-ray source of the system via a controller at one or more calibration positions based at least in part on at least one camera of the system. In such embodiments the X-ray source is disposed on a mobile arm and operative to transmit X-rays through the subject, and a field of view of the X-ray source is directed substantially towards the detector at each of the calibration positions.

  • Publication number: 20110145274
    Abstract: Systems, methods and mediums with instructions for viewing medical data are provided. A system for viewing medical data can include a computer processor, a database and a user interface. The database can include numerous entries from numerous clinical modalities. Each entry can include image data and/or non-image data. Each entry can include annotated medical information from a previous study. The annotated medical information can include comments and markings. The database can be searchable to identify an entry based on input medical information relating to a current study. The user interface can be configured to simultaneously display annotated medical information from an identified entry and medical information from the current study. The system can further include a second user interface configured to display medical information, allow a user to annotate the medical information, and allow the user to save the annotated medical information as an entry in the database.
