Disclosed herein are implementations for a digital stereoscopic display and digital loupes utilizing the digital stereoscopic display. The stereoscopic display may include display of magnified images.

Stereoscopic display and digital loupe for augmented-reality near-eye display

Apparatus, consisting of a hinge () defining a hinge axis (), and a pair of opposing jaws (A,B), including a movable jaw and a fixed jaw having a predetermined part radiopaque, so that the fixed jaw location is identifiable from a fluoroscopic image of the fixed jaw. The opposing jaws terminate at proximal and distal regions, and the proximal regions are connected to the hinge so that the movable jaw rotates about the hinge between a closed state and an open state. The jaws are curved in planes parallel to the hinge axis, and terminate in narrowed ends at the distal regions, so that in the closed state the jaws grip sections of vertebrae. The apparatus also has a support structure () that retains the hinge and the pair of opposing jaws, and a multiplicity of sharp teeth () disposed on respective inner surfaces of the opposing jaws.

Spinous process clamp

Disclosed herein are systems, devices, and methods for image-guided surgery. Some systems include a head-mounted unit, having a see-through augmented-reality display and a depth sensor, which is configured to generate depth data with respect to a region of interest (ROI) of a body of a patient that is viewed through the display by a user wearing the head-mounted unit. A processor, which is configured to receive a three-dimensional (3D) tomographic image of the body of the patient, computes a depth map of the ROI based on the depth data generated by the depth sensor, to compute a transformation over the ROI so as to register the tomographic image with the depth map, and to apply the transformation in presenting a part of the tomographic image on the display in registration with the ROI viewed through the display.

Augmented-reality surgical system using depth sensing

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.

Mirroring in image guided surgery

A registration marker comprising a radiotransparent substrate and a pattern formed in at least two dimensions, which is disposed on the substrate and is optically visible. The registration marker also has a multiplicity of radiopaque elements, which are disposed in the substrate and are spatially arranged in at least two dimensions to provide a unique pattern.

Registration of a fiducial marker for an augmented reality system

A tool adapter, consisting of an adapter arm having a proximal end terminating with a connection and a distal end having a circular coupling, the circular coupling having a center and defining an axis orthogonal to the circular coupling and passing through the center. The adapter also has a tool grip rotatingly connected to the circular coupling so as to permit rotation of the tool grip about the axis, the tool grip being configured to fixedly retain a tool along the axis.

Universal tool adapter

Apparatus, including a retaining structure (), positioned near a subject's eye that has a pupil with a diameter, an optical combiner (A) mounted on the structure before the eye, and a pixelated screen (A) having an array of variably transparent pixels coating the combiner. There is an image capturing device (A) mounted on the structure to capture an image of a scene viewed by the eye, and a projector (A) 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 () 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.

Combining video-based and optic-based augmented reality in a near eye display

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.

Tracking systems and methods for image-guided surgery

A marker () for image guided surgery, consisting of a base (), having a base axis, connecting to a clamp (), and an alignment target (). The alignment target includes a target region () having an alignment pattern formed thereon, and a socket () connected to the target region and configured to fit rotatably to the base, whereby the alignment target is rotatable about the base axis. The alignment target also includes an optical indicator () for the socket indicating an angle of orientation of the alignment target about the base axis.

Rotating marker for image guided surgery

A medical marking device, consisting of a radiotransparent plate having a first plurality of radiopaque elements embedded therein in a first predefined pattern and a second plurality of optical reflectors positioned on a surface in proximity to the plate in a second predefined pattern. The device also includes a sigmoid mounting arm having a first end connected to the radiotransparent plate and a second end containing one or more fastening receptacles.

Fiducial marker

Disclosed herein is a near eye assembly having a retaining structure (e.g., a spectacle frame or head up display mounted on a helmet) that is configured to be positioned in proximity to the eye of a user of the assembly. An optical combiner may be mounted on the retaining structure in front of the user eye. The optical combiner may at least partially transmit elements of a scene in front of the assembly through the combiner. In addition, the optical combiner may receive a visible radiation transmission derived from a scene, and/or a visual transmission such as a presentation of data or a marker, and redirect the transmission back to the user's eye.
