Patent number: 12383369Abstract: An imaging system, including a head-mounted display worn by a system operator. A marker defines a plane when attached to a human subject. Optically reflective elements are disposed on the marker and on opposing sides of the plane in a non-symmetrical arrangement with respect to the plane. A memory stores a graphical representation of a tool used in a procedure performed on the human subject, and an image of anatomy of the human subject. A camera attached to the display acquires an image of the marker and the tool. A processor analyzes the image to identify the plane and to identify a side of the plane wherein the camera is located, and to render to the display the image of the anatomy of the human subject with the graphical representation of the tool superimposed thereon from a point of view in the identified side of the plane.Type: GrantFiled: July 13, 2023Date of Patent: August 12, 2025Assignee: AUGMEDICS LTD.Inventors: Nissan Elimelech, Stuart Wolf, Nitzan Krasney

Patent number: 12206837Abstract: Apparatus, including a retaining structure (54), positioned near a subject's eye that has a pupil with a diameter, an optical combiner (52A) mounted on the structure before the eye, and a pixelated screen (60A) having an array of variably transparent pixels coating the combiner. There is an image capturing device (68A) mounted on the structure to capture an image of a scene viewed by the eye, and a projector (64A) is mounted on the structure to project at least one of a portion of the captured image and a stored image onto a section of the screen at a selected location thereof. A processor (26) renders the screen section at least partially opaque, selects the section location in response to a region of interest in the scene identified by analysis of the captured image, and determines a dimension of the section in response to the pupil diameter.Type: GrantFiled: July 13, 2023Date of Patent: January 21, 2025Assignee: AUGMEDICS LTD.Inventors: Nessi Benishti, Nissan Elimelech, Stuart Wolf, Elazar Gerland

Patent number: 12201384Abstract: Apparatus and methods are described including tracking a tool portion and a patient marker from a first line of sight, using a first tracking device disposed upon a first head-mounted device that includes a display. The tool portion and the patient marker are tracked from a second line of sight, using a second tracking device. When a portion of the patient marker and the tool portion are both within the first line of sight, an augmented reality image is generated upon the first display based upon data received from the first tracking device and without using data from the second tracking device. When at least the patient marker portion and the tool portion are not both within the first line of sight, a virtual image of the tool and anatomy of the patient is generated using data received from the second tracking device. Other applications are also described.Type: GrantFiled: April 10, 2024Date of Patent: January 21, 2025Assignee: AUGMEDICS LTD.Inventors: Stuart Wolf, Nissan Elimelech

Patent number: 12150821Abstract: A patient marker couples to an anchoring device via a base having a base axis, base connections and a first indicator. The marker includes: an adapter having a first surface with connections configured to mate with the base connections, and a second surface with connections congruent with the base connections, and at least one second indicator. The marker includes an alignment target, having a target region with an alignment pattern, and a socket connected to the target region with socket connections congruent with the first surface connections. In a first configuration the socket couples to the base by mating the first surface connections with the base connections and mating the socket connections with the second surface connections. In a second configuration, the socket fits onto the base by mating the socket connections with the base connections. One of the indicators indicates a target orientation angle about the base axis.Type: GrantFiled: July 29, 2021Date of Patent: November 26, 2024Assignee: AUGMEDICS LTD.Inventors: Tomer Gera, Nissan Elimelech
