摘要： Methods and systems for providing feedback during a medical procedure. The 3D position and orientation of a tracked tool are determined, relative to a site of the medical procedure, based on tracking information received from a tracking system. The 3D position and orientation are mapped to a common coordinate space, to determine the 3D position and orientation relative to a field-of-view (FOV) of an optical camera that is capturing an optical image of the site. Navigational information associated with the 3D position and orientation is determined. A virtual representation of the navigational information overlaid on the FOV and displayed. The displayed virtual representation is updated when the 3D position and orientation of the tracked tool changes or when the FOV changes, in accordance with the change.

摘要： Methods and systems for outputting depth data during a medical procedure on a patient. Depth data is outputted, representing at least one of relative depth data and general depth data. Tracking information about the position and orientation of a medical instrument and depth information about variations in depth over a site of interest are used. Relative depth data represents the depth information relative to the position and orientation of the instrument. General depth data represents the depth information over the site of interest independently of the position and orientation of the instrument.

摘要： A fiducial marker to be tracked by a surgical navigation system. The fiducial marker is to be affixed to an object during a surgical procedure. The fiducial marker including a casing for attachment to the object; a light emitting component attached to the casing; a power source within the casing; a signal receiver to receive a signal from the surgical navigation system; and control logic to control the light emitting component in response to the signal from the surgical navigation system. The object to-be-tracked may include a plurality of the fiducial markers arranged in geometric pattern, and the markers may include a first active fiducial marker having a first light emitting component that emits light having a first spectral bandwidth, and a second active fiducial marker having a second light emitting component that emits light having a second spectral bandwidth different from the first spectral bandwidth.

摘要： A medical navigation system is provided for registering a patient for a medical procedure with the medical navigation system using fiducial markers. The fiducial markers are placed on the patient prior to a 3D scan and the fiducial markers each have a target for use with a tracking system. The medical navigation system comprises a 3D scanner, a tracking system, a display, and a controller electrically coupled to the 3D scanner, the tracking system, and the display. The controller has a processor coupled to a memory. The controller is configured to: receive 3D scan data generated by the 3D scanner representative of a 3D scan of at least a portion of the patient, the 3D scan including the fiducial markers visible by the 3D scanner; load from the memory saved medical image data, the saved medical data including preoperative image data saved during a previous scan of at least a portion of the patient; receive position data from the tracking system based on the target for each of the fiducial markers; and perform a transformation mapping to create a single unified virtual coordinate space based on the 3D scan data, the position data, and the medical image data, and updating registration data of the medical navigation system based on the transformation mapping.

摘要： A method and computing device for displaying surgical path data are provided. The computing device includes an input device, a display, a memory and a processor. The memory stores (i) an image of a volume of patient tissue having an outer surface, and (ii) anatomical data defining anatomical features of the volume. The processor receives an identifier of a target location within the volume; generates a plurality of paths from the outer surface to the target location, each path having a start point located on the outer surface, and an end point at the target location; for each of the plurality of paths, determines a score based on a comparison between the path and the anatomical data; and controls the display to present the outer surface and, at the locations of the start points, indications of the respective scores of the paths corresponding to the start points.

摘要： A method and system to generate an operating room layout plan for a surgical procedure involving a patient and a trajectory of access. A patient model is positioned in a virtual coordinate space representing the operating room, and is rendered, along with the trajectory of access relative to the patient, on a display. The trajectory of access defines a zone of operation in the virtual coordinate space. The planning system receives selection of a navigation camera location in the virtual coordinate space; renders a navigation camera model visually indicating an operative field of view; determines whether the navigation camera has a direct line-of-sight to the zone of operation and, if not, indicates an error; and outputs the operating room layout plan based on the location of the models in the virtual coordinate space.

摘要： A processing system for and a method of segmenting a physiological image is provided. Once the physiological image is received, extrinsic data defining extrinsic regions is further received. Additionally, intrinsic data defining at least one intrinsic region, each intrinsic region corresponding to one extrinsic region is received. A primary modification is performed, where a shape and size of at least one extrinsic region having a corresponding intrinsic region is modified based on a shape and size of the corresponding intrinsic region, to form a modified extrinsic data. The physiological image is segmented into segmented regions based on the modified extrinsic data, each segmented region which has a corresponding intrinsic region representing a primary modification based on the corresponding intrinsic region.
