A registration fixture or plate is configured for use with a medical imaging system. The registration fixture may be an optical magnetic registration plate including a plurality of fiducial markers in arranged in a predefined unique pattern. The pattern can be unambiguously detected on 2D image of the plate produced by the medical imaging system. Association of the 2D imaged pattern of fiducial markers with the actual 3D pattern on the optical magnetic registration plate allows for accurate calculation of projection matrices and co-registration of the 3D and 2D coordinate systems.

A surgical system includes an arm extending from the base and having a distal end configured to be coupled to a tool, a first marker coupled in fixed relation to the base, and a tracking system. The tracking system is configured to collect first data indicative of a position of the first marker and collect second data indicative of a position an anatomical feature of a patient. The surgical system also includes a processor configured to calculate a position of the tool relative to the anatomical feature based on the first data and the second data.

A head stabilization device or HFD includes a plurality of integrated markers. The HFD may be in the form of a skull clamp, vacuum bag, combinations thereof, or other supporting structure. The integrated markers include MRI markers detectable by an MRI scanner and fiducial markers detectable by a registration tool of a navigation system. The markers provide a reference point relative to an operation site in a patient for use in a navigation guided procedure and aid in registering or calibrating the location of the patient with captured images used in the navigation guided procedure.

A stable affixation system for dental implantation includes a fixation tray having, for rapid placement, a housing defining a chamber whose inner surface is configured to house a flowable or malleable material and be placed over one or more teeth during guided dental implantation surgery. A central portion not configured to flex is situated between housing side walls. Each such side wall has an upper side portion and a lower side portion. Without the lock a squeezing force on the upper side portions flexes the lower side portions outward. The lock urges the upper side portions outward so as to flex the lower side portions inward. The lock reduces or eliminates freedom of movement of the tray. The system allows rapid removal and is sturdy enough to withstand forces including from various angles and leverage. The central portion may hold registration elements.

Methods and system for characterizing ligament properties using elastography are disclosed. An ultrasound system capable of performing shear wave elasticity imaging and/or supersonic shear imaging may retrieve one or more images from a proposed surgical site. The one or more images may be provided to a surgical planning system that identifies one or more properties of ligaments proximate to the surgical site. Musculoskeletal simulations may be performed using the identified properties to preoperatively identify a surgical plan. Preoperative identification of a surgical plan may enable a surgeon to select from more fine-tuning options for a joint replacement than conventional systems.

A method for visualizing and targeting anatomical structures inside a patient utilizing a handheld screen device may include grasping the handheld screen device and manipulating a position of the handheld screen device relative to the patient. The handheld screen device may include a camera and a display. The method may also include orienting the camera on the handheld screen device relative to an anatomical feature of the patient by manipulating the position of the handheld screen device relative to the patient, capturing first image data of light reflecting from a surface of the anatomical feature with the camera on the handheld screen device, and comparing the first image data with a pre-operative 3-D image of the patient to determine a location of an anatomical structure located inside the patient and positioned relative to the anatomical feature of the patient.

A method includes obtaining, via one or more processors, three-dimensional data representing a patient's bone, obtaining, via the one or more processors, three-dimensional data representing at least portions of a patient specific bone jig, the patient specific bone jig having an inner surface portion matched to an outer surface portion of the patient's bone, obtaining, via the one or more processors, image data representing the at least portions of the patient specific bone jig registered to the patient's bone, and generating, via the one or more processors, data representing a location and an orientation of the patient's bone based on the obtained image data, the obtained three-dimensional data representing the patient specific bone jig, and the obtained three-dimensional data representing the patient's bone. In another embodiment, a patient specific bone jig with predetermined spatial indicia registered to a portion of the patient's bone may be employed with point sampling.

The present invention provides a robotic navigation system for identifying a target nerve for guiding and/or performing the implanting a neuromodulation device at the target nerve wherein the neuromodulation device includes a pulse generator and at least one lead in electrical or operative connection with the pulse generator. In some embodiments, the location of the robotically advanced lead and electrode may be imaged and displayed on a display and/or may be visually annunciated using one or more lights to indicate whether the placement location of the lead or electrode is within or outside of a predetermined distance of the target nerve.

Mediated-reality imaging systems, methods, and devices are disclosed herein. In some embodiments, an imaging system includes a camera array configured to (i) capture intraoperative image data of a surgical scene in substantially real-time and (ii) track a tool through the scene. The imaging system is further configured to receive and/or store preoperative image data, such as medical scan data corresponding to a portion of a patient in the scene. The imaging device can register the preoperative image data to the intraoperative image data, and display the preoperative image data and a representation of the tool on a user interface, such as a head-mounted display.

A computer assisted surgical system that includes an apparatus for imaging a region of interest of a portion of an anatomy of a subject; a memory containing executable instructions; and a processor programmed using the instructions to receive two or more two-dimensional images of the region of interest taken at different angles from the apparatus and process the two or more two-dimensional images to produce three dimensional information associated with the region of interest.
