1. A method of using a medical imaging scanner comprising:
under the control of a processor,
obtaining a digital image of the medical imaging scanner from a camera;
identifying by the processor a pose of a gantry of the medical imaging scanner based on the obtained digital image, the gantry including a movable C-arm supporting an imaging signal transmitter and a detector panel that are movable along an arc relative to a station;
predictively determining a range of motion of the movable C-arm along the arc based on the pose without moving the movable C-arm;
generating a graphical object based on the predictive determination of the range of motion and the pose, wherein the graphical object indicates a clearance region that will not be contacted by the imaging signal transmitter and the detector panel during imaging; and
displaying the generated graphical object on an augmented reality (AR) display device as an overlay to the medical imaging scanner,
wherein the step of displaying the graphical object on the AR display device includes providing an arcuate object for display as an overlay relative to the gantry and with a pose that indicates the range of motion of the at least one of the imaging signal transmitter and the detector panel along the arc, and
wherein the step of providing the arcuate object for display includes providing a circular object for display as an overlay relative to the gantry and with a pose that indicates an interior region of the movable C-arm that will not be contacted by the at least one of the imaging signal transmitter and the detector panel when moved along the arc through the range of motion.
