Creating surgical annotations using anatomy identification
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.
1. A method of marking and tracking anatomic features on an image display, comprising:
capturing a digital image of a treatment site in a region of patient anatomy;
displaying the digital image on an image display;
receiving user input marking an anatomic region of interest on the image display;
displaying an overlay marking the anatomic region of interest, said overlay comprising a three-dimensional geodesic mesh;
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;
in response to user input, panning the displayed image such that the anatomic region of interest is outside of the displayed field;
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.
2. The method of claim 1 , wherein the anatomic region of interest is an organ.
3. The method of claim 2 , wherein the organ is a bladder.
4. The method of claim 2 wherein the organ is a uterus.
