Abstract: Methods of respiration compensation including detecting a position of a catheter proximate a target within a patient, performing a local registration to update a displayed relative position and orientation of the catheter and the target in a three-dimensional model, detecting movement of a plurality of sensors, determining a respiration waveform from the detected movement of the plurality of sensors, and indicating on a user-interface a period during which advancement of a biopsy or therapy tool from the catheter is most likely to intersect the target, wherein the period corresponds to a portion of the respiration waveform during which the movement of the plurality of sensors is within a desired range.

Abstract: Imaging systems and methods estimate poses of a fluoroscopic imaging device, which may be used to reconstruct 3D volumetric data of a target area, based on a sequence of fluoroscopic images of a medical device or points, e.g., radiopaque markers, on the medical device captured by performing a fluoroscopic sweep. The systems and methods may identify and track the points along a length of the medical device appearing in the captured fluoroscopic images. The 3D coordinates of the points may be obtained, for example, from electromagnetic sensors or by performing a structure from motion method on the captured fluoroscopic images. In other aspects, a 3D shape of the catheter is determined, then the angle at which the 3D catheter projects onto the 2D catheter in each captured fluoroscopic image is found.

Abstract: A method for placing a set of one or more markers in a luminal network in a patient's body includes using at least one hardware processor for receiving image data of the anatomy of a luminal network of a patient and a location of at least one target in the luminal network anatomy, obtaining a rule set defining one or more rules for placing the set of one or more markers in the luminal network anatomy and with respect to the at least one target, during a survey performed by a user via a navigation module in a portion of the luminal network surrounding the at least one target, acquiring, via the navigation module, sample-locations in the surveyed portion of the luminal network, and identifying a set of one or more marker locations for placing the set of one or more markers from the acquired sample-locations, which complies with the rule set.

Abstract: A system and method for navigation of a luminal network including receiving a computed tomography (CT) image data set, generating a three-dimensional (3D) model, displaying the 3D model in a user-interface on a display operatively connected to the computing device, and receiving an indication of a location of a tumor in the CT image data set. The system and method further including displaying the location of the tumor in the 3D model, receiving an indication of a margin around the tumor to achieve a desired therapy, generating a pathway to the tumor for navigation of a catheter, receiving a location of a sensor associated with a navigation catheter and registering the CT image data set with a luminal network of a patient, displaying the location of the sensor within the 3D model that substantially corresponds to the location of the sensor within the luminal network of the patient.

Abstract: Systems and methods of estimating movement of anatomical structures of a new patient include learning one or more deformation models from preoperative and intraoperative imaging data of a set of other patients and estimating movement of anatomical structures of the new patient based on the one or more deformation models and preoperative imaging data of the new patient. Estimating movement of the anatomical structures may include applying deformation models to map data derived from preoperative imaging data of a new patient to obtain deformed map data for each deformation model, and determining the deformation model that best fits the intraoperative imaging data of the new patient. Applying a deformation model to map data may include applying a transformation to the deformation model and interpolating to obtain a deformed map data. Registration is computed between locations of a medical device sampled during navigation of the medical device through the new patient and the original and deformed map data. The map data which fits the 3D locations the best is applied to the targets of the new patient.
