Abstract: System and method for determining the position and orientation (P&O) of a tool-tip relative to an eye tissue of interest. The system includes and imaging and tracking module coupled with a processor. The imaging and tracking module at least includes an imager. The imager acquires at least one image of at least one tissue-reference-marker. The imaging and tracking module further determines information relating to the P&O of the tool. The processor determines the P&O of the tissue-reference-marker according to the acquired image of the tissue-reference-marker. The processor determines the P&O of the eye tissue of interest, according to the P&O of the tissue-reference-marker, and a predetermined relative P&O between the tissue-reference-marker and the eye tissue of interest. The processor also determines the P&O of a tool-tip according to a tool-marker and determines the relative P&O between the tool-tip and the eye tissue of interest.

Abstract: A system captures and displays video of surgeries. The system may include at least one digital image sensor optically coupled to one or more lenses and configured to capture a video sequence of a scene in a surgery; at least one interface configured to receive at least one region on interest (ROI) of the captured video sequence; an electronic display, selected so that at least one of the digital image sensors has a pixel resolution which is substantially greater than the pixel resolution of the electronic display; and a computer processor configured to: receive the at least one captured video sequence and the at least one received ROI and display over the at least one electronic display a portion of the captured video sequence based on the at least one selected ROI.

Abstract: System and method for presenting magnified images locked onto object of interest in operator environment. A camera disposed on head of operator captures images of scene, where camera moves in conjunction with head movements. A head tracker detects the operator LOS by detecting at least head orientation. A processor obtains designated coordinates of object of interest in scene, and determines relative angle between detected operator LOS and object. The processor determines coordinates of object in acquired images, and applies image processing for fine stabilization of images based on previous images so as to compensate for operator head movements. The processor rescales an image region surrounding object of interest, in accordance with at least one display parameter, to produce respective magnified image frames of object. A head-mounted display displays the magnified images to operator such that object of interest appears in a defined position on display regardless of operator head movements.
