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.
