Abstract
A system and method allow creation of surgical annotations during surgery. A digital image of a treatment site in a region of patient anatomy is captured using a camera and is displayed on an image display. The system displays an overlay marking an anatomic region of interest in the displayed image. During the course of the surgery, panning of the image results in the anatomic region of interest being outside the displayed field of view. In response to user input, the displayed image is subsequently panned such that the anatomic region of interest and the displayed overlay return to the displayed field of view.
Core Innovation
The invention relates to a method of marking and tracking anatomic features on an image display by capturing a digital image of a treatment site in a region of patient anatomy and displaying the digital image on the image display. A user input marks an anatomic region of interest on the image display, and an overlay marking the anatomic region of interest is displayed, the overlay comprising a three-dimensional geodesic mesh.
The overlay deforms in response to deformation of tissue of the anatomic region of interest. If the deformation of the tissue crosses a predetermined distortion threshold, the overlay disappears from the image display. The overlay behavior responds to tissue deformation and can be hidden when the distortion threshold is exceeded.
In response to user input, the displayed image is panned such that the anatomic region of interest is outside of the displayed field, and in response to user input, the displayed image is panned such that the anatomic region of interest and the displayed overlay returns to the displayed field.
Claims Coverage
The document provides one independent claim directed to a marking-and-tracking method for anatomic regions of interest using a three-dimensional geodesic mesh overlay that deforms with tissue motion and can disappear past a distortion threshold, while also allowing user-driven panning to move the region and overlay in and out of the displayed field. Dependent claims further narrow the anatomic region of interest to an organ, including specific examples of bladder and uterus.
Three-dimensional geodesic mesh overlay for anatomic region of interest
Displaying an overlay marking the anatomic region of interest, the overlay comprising a three-dimensional geodesic mesh.
Overlay deformation with tissue deformation and disappearance past distortion threshold
Causing the overlay to deform in response to deformation of tissue of the anatomic region of interest and, if deformation of the tissue crosses a predetermined distortion threshold, causing the overlay to disappear from the image display.
User-driven panning to move region and overlay out of and back into view
In response to user input, panning the displayed image such that the anatomic region of interest is outside of the displayed field; and in response to user input, panning the displayed image such that the anatomic region of interest and the displayed overlay returns to the displayed field.
Across the independent claim, the core inventive coverage centers on using a three-dimensional geodesic mesh overlay that deforms with tissue deformation and is removed when a predetermined distortion threshold is crossed, combined with user-driven panning that moves the anatomic region of interest and the overlay in and out of the displayed field. Dependent claims restrict the anatomic region of interest to an organ, including bladder and uterus.
