    Abstract: The present disclosure relates to calibration target devices, assemblies and methods for use with imaging systems, such as a stereoscopic endoscope. A calibration assembly includes: a target surface extends in three dimensions with calibration markers and a body with an interface that engages an endoscope so the markers are within the field of view. A first calibration marker extends along a first plane of the target surface and a second marker extends along a second plane of the target surface. The planes are different and asymmetric relative to the field of view as seen through the endoscope. Three-dimensional targets, in particular, enable endoscopic calibration using a single image (or pair of images for a stereoscopic endoscope) to reduce the calibration process complexity, calibration time and chance of error as well as allow the efficient calibration of cameras at different focus positions.

    Abstract: Information extracted from sequential images captured from the perspective of a distal end of a medical device moving through an anatomical structure are compared with corresponding information extracted from a computer model of the anatomical structure. A most likely match between the information extracted from the sequential images and the corresponding information extracted from the computer model is then determined using probabilities associated with a set of potential matches so as to register the computer model of the anatomical structure to the medical device and thereby determine the lumen of the anatomical structure which the medical device is currently in. Sensor information may be used to limit the set of potential matches. Feature attributes associated with the sequence of images and the set of potential matches may be quantitatively compared as part of the determination of the most likely match.

    Abstract: Systems and methods for supporting image-guided procedures include a device having an instrument usable to collect location data for one or more passageways and one or more processors coupled to the instrument. The one or more processors are configured to organize a plurality of points within the location data based on a corresponding insertion depth of the instrument when each of the plurality of points is collected, create a passageway tree based on the points, identify at least three non-collinear landmark locations within the passageway tree, create a seed transformation between one or more of the at least three non-collinear landmark locations and corresponding model locations in model data, and register, using the seed transformation, the plurality of points to the model data for the one or more passageways. In some embodiments, the at least three non-collinear landmark locations are based on a main branch point in the passageway tree.
