摘要： A flexible high resolution endoscope is provided herein. The endoscope comprises: a plurality of optical fiber bundles; a plurality of lenses in a one-to-one relationship with the plurality of optical fiber bundles; and, a plurality of cameras in a one-to-one relationship with the plurality of optical fiber bundles, each respective optical fiber bundle, of the plurality of optical fiber bundles, having a respective lens, of the plurality of lenses, located at a respective distal end, and a camera, of the plurality of cameras, located at a respective proximal end, the plurality of optical fiber bundles being coupled together at a common distal end, and otherwise being uncoupled from one another, a bending radius of the endoscope defined by a largest respective bending radius of each of the plurality of optical fiber bundles.

摘要： Methods and systems for providing feedback during a medical procedure are provided. A saved optical image of a field of view (FOV) of a site of the medical procedure is obtained along with a live optical image of the FOV of the site during the medical procedure. Navigational information relative to the site of the medical procedure is determined. The navigational information is then mapped to a common coordinate space, to determine the navigational information relative to the FOV of the saved and live optical images of the surgical site. Virtual representations of the navigational information is overlaid on the saved and/or live optical images and displayed on at least one display.

摘要： A method and device for tracking objects by surgical navigation systems. The method includes: capturing an image of the tracked object; determining whether a unique identifiable feature associated with at least one totem pattern is discernible in the image; when the unique identifiable feature is discernible: determining a position or an orientation of the tracked object based on the at least one totem pattern; and registering the at least one totem pattern in the surgical coordinate space; and when the unique identifiable feature is indiscernible: determining a position of each totem pattern relative to other totem patterns such that a combination of totem patterns within the captured image is a marker group detectable as a composite totem pattern; determining a position or an orientation of the tracked object based on the composite totem pattern associated with the tracked object; and registering the composite totem pattern in the surgical coordinate space.
