    摘要: An endoscopic camera has two or more cameras positioned at a distal end, positioned to provide partially overlapping fields of view. The cameras communicate captured digital images the length of the flexible endoscope, where they may be saved and processed to provide additional imaging features. With partially overlapping images from two or more cameras, image processing can provide panoramic images, super resolution images, and three-dimensional images. One or more of these image modes may also be enhanced to provide a virtualization window that displays a portion of a larger or higher resolution image. The virtualization window displays the selected area of the image, and may be moved or zoomed around the image to provide a virtual endoscope repositioning experience, where the endoscope remains statically positioned but the virtualization window presents a sense of movement and navigation around the surgical area.

    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. The IGS system may be configured to detect various movement patterns of the tools, which may be mapped to and associated with corresponding actions or inputs to the IGS system. In one example, a registration probe may be moved along the x-axis and y-axis, with detected movements identified and received by the IGS system as movements of a mouse cursor on a display of the IGS system. In another example, the registration probe may be moved in a circular pattern, or quickly moved along any of the x-axis, y-axis, or z-axis, with each being configured to cause the IGS system to zoom a display, change a view, record video, or other actions.

    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.
