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.

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 for determining a position of a tool-point-of-interest of a tool, relative to an eye-tissue-of-interest, which includes and imager a tool-tracker and a processor. The imager acquires an image of a tissue-reference-marker. The tool-tracker determines information relating to the P&O of the tool in a reference-coordinate-system. The imager and the tool-tracker are in registration with the reference-coordinate-system. The processor determines the position of the tissue-reference-marker in the reference-coordinate-system, according to the acquired image of the tissue-reference-marker. The processor determines the P&O of the eye-tissue-of-interest in the reference-coordinate-system according to at least the position of the tissue-reference-marker and a relative position between the tissue-reference-marker and the eye-tissue-of-interest. The relative position is pre-determined from a stored-3D-model. The processor determines the position of a tool-point-of-interest in the reference-coordinate-system from the P&O of the tool in the reference-coordinate-system. The processor also determines a relative position between the tool-point-of-interest and the eye-tissue-of-interest.

Abstract: Imaging systems and methods are provided, which implement wide field imaging of a region for medical procedures and provide tracking of tools and tissues in the whole region while providing digitally magnified images of a portion of the captured region. Optical tracking may be implemented by stereoscopic imaging, and various elements may be optically tracked such as various markers and fiducials, as well as certain shapes and objects which are optically identifiable by image processing.

Abstract: A novel surgical lens system including a lens and a reflective element. The lens is placed on, or above, a cornea of an eye of a subject for enabling inspection of the eye. The reflective element is incorporated into the lens. The reflective element reflects a light beam toward the eye of the subject. The reflective element increases the divergence of the light beam, such that the divergence of the reflected light beam is larger than the divergence of the light beam. The light beam is emitted by a non-invasive light source positioned externally to the eye.
