An electromagnetic catheter and navigation system may include an umbilical catheter including a first electromagnetic sensor having five degrees of freedom disposed in the tip of the umbilical catheter; an ultrasound imaging system including an ultrasound probe including a second sensor; a non-contact electromagnetic field generator; a sensor interface unit in operable communication with the first electromagnetic sensor; a sensor control unit in operable communication with the sensor interface unit and the non-contact field generator; and a computing device in operable communication with the sensor control unit and the ultrasound imaging system. The system may be constructed and arranged to monitor the location and position of an umbilical catheter after insertion into an umbilical vessel via displaying on a computing device at least one of two-dimensional or three-dimensional imagery indicating the position of the umbilical catheter.

Systems and methods for capturing and rendering light fields for head-mounted displays are disclosed. A mediated-reality visualization system includes a head-mounted display assembly comprising a frame configured to be mounted to a user's head and a display device coupled to the frame. An imaging assembly separate and spaced apart :from the head-mounted display assembly is configured to capture light-field data. A computing device in communication with the imaging assembly and the display device is configured to receive light-field data from the imaging assembly and render one or more virtual cameras. Images from the one or more virtual cameras are presented to a user via the display device.

An ultrasound imaging device (10) with an ultrasound probe (12) acquires a live ultrasound image which is displayed with a contour (62) or reference image (60) registered with the live ultrasound image using a composite transform (42). To update the composite transform, the ultrasound imaging device acquires a baseline three-dimensional ultrasound (3D-US) image (66) tagged with a corresponding baseline orientation of the ultrasound probe measured by a probe tracker, and one or more reference 3D-US images (70) each tagged with a corresponding reference orientation. Transforms (54) are computed to spatially register each reference 3D-US image with the baseline 3D-US image. A closest reference 3D-US image is determined whose corresponding orientation is closest to a current orientation of the ultrasound probe as measured by the probe tracker. The composite transform is updated to include the transform to spatially register the closest reference 3D-US image to the baseline 3D-US image.

The present invention features an all-in-one system for vascular access and closure. In particular, this invention features systems and methods for forming holes in blood vessels and rapidly closing these vessel holes using an all-in-one system. For example, an arterial access and closure port system is disclosed herein to provide fail-safe percutaneous entry and exit into any artery, particularly useful for high flow and high pressure arteries such as the carotid artery. The present invention is a single system that forms and closes vascular holes and can be used for percutaneous arterial access with interventional radiology, interventional cardiology, neuro-intervention, endovascular surgery, and endovascular neurosurgery.

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.

A system for tracking an instrument with ultrasound includes a probe (122) for transmitting and receiving ultrasonic energy and a transducer (130) associated with the probe and configured to move with the probe during use. A medical instrument (102) includes a sensor (120) configured to respond to the ultrasonic energy received from the probe. A control module (124) is stored in memory and configured to interpret the ultrasonic energy received from the probe and the sensor to determine a three dimensional location of the medical instrument and to inject a signal to the probe from the transducer to highlight a position of the sensor in an image.

Systems and methods for assisting users with accurate tool identification. A tool includes a tool feature, and a navigation system includes a localizer to detect a position of the tool feature. A memory stores identification data associated with a plurality of tools. Controller(s) is/are coupled to the navigation system, the memory and the display. The controller(s) receive, from the localizer, the detected position of the tool feature and compare the detected position of the tool feature with the identification data stored in the memory to determine an identity of the tool. The controller(s) present, on a display, the identity of the tool and an identity of at least one other tool.

Methods, non-transitory computer readable media, serial monitor devices, fiducial tracking knee braces devices, and systems that facilitate generation of improved three-dimensional models from two-dimensional multi-planar images are disclosed. With this technology, correspondence of a patient's knee angle is substantially maintained across x-ray images to improve fiducial-marker-to-bone relationships within the images and facilitate improved scaling and registration of the images to generate a three-dimensional model of the knee. In particular, orientation sensor(s) attached to an improved knee brace device allows a user to substantially match the position of the knee across anterior/posterior and lateral x-ray images so that the images can be scaled and oriented more effectively, resulting in more accurate three-dimensional models and improved preoperative planning for patients.

A surgical robotic system having multiple robotic arm carts and a surgeon console including a processor and a memory. The memory including instructions stored thereon, which when executed by the processor cause the surgical robotic system to receive data indicating a first pose of the first movable cart and a second pose of the second movable cart and determine a relative location of the first movable cart and the second movable cart based on the first pose and the second pose.

A rotary tool includes a tool body and a powered rotary cutting tooltip that is oriented and positioned relative to the tool body by a plurality of processor-controlled actuators that provide degrees of freedom. The processor uses a surgical tracking system to identify the pose of the tool body and the tooltip relative to a patient's anatomy and controls the actuators to maintain the tooltip within a predetermined cutting plan to compensate for deviation of a surgeon's hand or a robotic arm controlling the tool body during a cutting operation.
