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： Tools used within a surgical area may be equipped with sensors that allow them to be tracked within the magnetic field of an image guided surgery (IGS) system. These tools may include a probe which is instrumented with a position sensor allowing it to be used not only for registration of non-magnetic objects within the magnetic field, but also for providing additional inputs.

摘要： A virtual camera may be positioned relative to a 3-D model of a patient anatomy in order to provide a virtual camera view of the surrounding anatomy and tracked surgical instruments being deployed to the anatomy. Visual context provided by the virtual camera may be limited in some cases, such as where a surgical instrument is being used within a very narrow anatomical passageway or cavity. To provide more placement flexibility, an IGS system providing a virtual camera receives inputs defining variable visual characteristics for different segments or regions of the 3-D model, which may include hiding certain segments or making certain segments semi-transparent. With such a system, the view of the 3-D model provided by the virtual camera view may be modified to remove or deemphasize less relevant segments, to display or emphasize more relevant segments (e.g., critical patient anatomy), or both.

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： 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： A method includes receiving locations of multiple ablation sites formed on a surface of a heart. Distances are measured among at least some of the ablation sites based on the locations. One or more gaps between the ablation sites, which meet an alerting criterion, are identified. The identified gaps are indicated to an operator.

摘要： Described embodiments include an apparatus that includes a display and processor. The processor is configured to receive, from a user, an input that indicates one or more points of interest on an electroanatomical map, of an anatomical surface, that is displayed on the display, and to superimpose on the map, in response to the input, a plurality of contours, each one of the contours being at a different respective geodesic distance, with respect to the surface, from the points of interest. Other embodiments are also described.

摘要： A method, consisting of receiving a computerized tomography scan of at least a part of a body of a patient, and identifying voxels of the scan that correspond to regions in the body that are traversable by a probe inserted therein. The method also includes displaying the scan on a screen and marking thereon selected start and termination points for the probe. A processor finds a path from the start point to the termination point consisting of a connected set of the identified voxels. The processor also uses the scan to generate a representation of an external surface of the body and displays the representation on the screen. The processor then renders an area of the external surface surrounding the path locally transparent in the displayed representation, so as to make visible on the screen an internal structure of the body in a vicinity of the path.

摘要： A method, including receiving a computerized tomography (CT) image of voxels of a subject's head, and analyzing the image to identify respective locations of the subject's eyes in the image, so defining a first line segment joining the respective locations. The method includes identifying a voxel subset overlaying bony sections of the head, lying on a second line segment parallel to the first line segment and on a third line segment orthogonal to the first line segment. A magnetic tracking system configured to measure positions on the subject's head is activated, and a probe, operative in the system, is positioned in proximity to the bony sections to measure positions of a surface of the head overlaying the bony sections. A correspondence between the positions and the voxel subset is formed, and a registration between the CT image and the magnetic tracking system is generated in response to the correspondence.
