摘要： Apparatus, including a patient tracker, attached to a subject, having magnetic field sensors and optical landmarks with known spatial relationships to each other. A camera acquires a 3D optical image, in a first frame of reference (FOR), of the subject's face. A magnetic radiator assembly generates magnetic fields at the subject's head, thereby defining a second FOR. A processor: processes field sensor signals to acquire location coordinates of the sensors in the second FOR; segments a tomographic image of the subject, having a third FOR, to identify the subject's face in the third FOR; computes a first transformation between the third and first FORs to map the tomographic face image to the 3D optical image; maps the optical landmarks to the third FOR; maps the respective location coordinates of the sensors to the first FOR; and computes a second transformation between the second FOR and the third FOR.

摘要： An ablation instrument includes a shaft that extends from a grip portion. A curved portion of the shaft is shaped to allow insertion into the head of a patient, and to position an ablation tip that extends from a distal tip of the shaft proximate to an ablation target, such as the posterior nasal nerve. When activated the ablation tip projects radiofrequency energy to ablate nearby tissue. An ablation assistance features of an image guided surgery navigation system is configured to segment and identify ablation targets within a set of pre-operative images. When a position tracked ablation instrument is configured for use, the system begins to monitor the proximity of the ablation tip to the ablation targets. When the tip is within an effective distance of the target for ablation, the system provides an alert and activates the instrument so that RF energy may be projected.

摘要： A virtual endoscopic view shows a surgical area and surrounding anatomy and may also show a position of a surgical instrument in use during a surgical procedure, allowing a surgeon to virtually view the surgical area when direct viewing or actual endoscopic views are incomplete, obstructed, or otherwise unavailable or undesirable. In order to render the endoscopic view, an IGS navigation system may be configured with an observer point and an observer orientation within 3-D space based upon user inputs. A user interface for defining these points allows a user to view a virtual endoscopic preview in real-time while providing inputs, thus improving the likelihood that the resulting virtual endoscopic view is as desired by the user; and reducing time spent redefining and reconfiguring the virtual endoscopic view. The virtual endoscopic preview may provide combinations of static and dynamic images to illustrate the spatial relationship of the provided inputs.

摘要： Physicians performing invasive procedures require accuracy and precision when working with surgical tools. Surgical procedures are increasingly becoming minimally invasive, with physicians operating using cameras to view the surgery site and directing their tools through oculars or video displays. Ideally, the physician should be able to perform the invasive procedure while simultaneously observing both the real-time image of the patient and additional data critical for his medical decisions about the manipulation of the surgical tool and the next surgical step. The augmented reality navigation system of the present disclosure provides tool location visibility for invasive procedures through the use of location sensors included on a camera and/or on the tools used during a procedure. A location tracking system determines and monitors the locations of the tools and camera based on the characteristics of signals detected by the sensors and displays informational overlays on images obtained with a camera.

摘要： An apparatus includes a body, an upright member, a frame, and a plurality of field generating elements. The body is configured to be positioned between a patient's back and a backrest of a chair. The upright member extends upwardly from the body. The frame has a curved configuration configured to partially surround a patient's head. The field generating elements are configured to generate an electromagnetic field around a patient's head partially surrounded by the frame.

摘要： Physicians performing invasive procedures utilize instruments inserted into a human body to perform the procedures. Such procedures typically involve actions to be performed on specific targeted anatomical structures. During the procedure, nearby anatomical structures unrelated to the procedure should generally be avoided. A system and techniques are provided herein for monitoring the position of such unrelated nearby anatomical structures relative to one or more surgical instruments. The system emits a warning to a human operator such as a surgeon if one of the instruments is too close to a monitored anatomical structure.

摘要： A visualization system may be implemented with an image guided surgery navigation system for use during ENT procedures. Correlated datasets such as surgical paths and pre-operative image slices may be correlated with the coordinate system of the navigation system for reference during a procedure. A surgeon may wear a head mounted display (“HMD”) having a transparent screen through which the patient anatomy may be viewed. The orientation and distance of the head mounted display relative to the patient anatomy may be determined using magnetic position tracking, image analysis of images captured by a camera of the HMD, or both. Correlated datasets may then be transformed based on the relative distance and orientation and may be displayed via the transparent screen to overlay directly viewed patient anatomy. Some implementations may include optical fiducials integrated with a patient tracking assembly to aid in tracking the patient and determining perspective of the HMD.
