Abstract
An augmented reality system is provided for use with a medical imaging scanner. The AR system obtains a digital image from a camera, and identifies a pose of a gantry of the medical imaging scanner based on content of the digital image. The gantry includes a movable C-arm supporting an imaging signal transmitter and a detector panel that are movable along an arc relative to a station. A range of motion of the movable C-arm along the arc is determined based on the pose. A graphical object is generated based on the range of motion and the pose, and is provided to a display device for display as an overlay relative to the medical imaging scanner.
Claims19
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.
A method of using a medical imaging scanner with an augmented reality (AR) display device, the method comprising:
- under the control of a processor of a computer system:
- obtaining a digital image of the medical imaging scanner from the camera;
- identifying a pose of a gantry of the medical imaging scanner based on content of the 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;
- determining a range of motion of the movable C-arm along the arc based on the pose;
- generating a graphical object indicative of a clearance region based on the range of motion and the pose;
- and
- providing the graphical object to the AR display device for display as an overlay relative to the medical imaging scanner,
- wherein the step of providing the graphical object to 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.
