Abstract: A system is configured to perform operations includes accessing a set of model points of a model of an anatomic structure of a patient, the model points being associated with a model space. A set of measured points of the anatomic structure of the patient are collected, the measured points being associated with a patient space. The set of model points are registered to the set of measured points using a first set of initial parameters to generate a first transformation. One or more sets of perturbed initial parameters are generated based on the first set of initial parameters. One or more perturbed registration processes are performed to register the set of model points to the set of measured points using the one or more sets of perturbed initial parameters respectively to generate corresponding perturbed transformations. A registration quality indicator is generated based on the first transformation and the one or more perturbed transformations.

Abstract: A computer-assisted medical system comprises a fluoroscopic imager having a full scan range in a surgical coordinate space. The system further comprises one or more processors configured to perform a method. The method includes receiving a first fluoroscopic image data set of a patient anatomy. The first fluoroscopic image data set is obtained from the full scan range of the fluoroscopic imager. The method further includes receiving at least one additional fluoroscopic image data set of the patient anatomy from the fluoroscopic imager operating in a constrained range substantially smaller than the full scan range. The method further includes constructing a first planar tomographic image from the first and at least one additional fluoroscopic image data sets.

Abstract: A system includes one or more processors configured to read instructions to cause the system to perform operations including accessing a set of model points of a model of an anatomic structure of a patient. The model points is associated with a model space. The operations further include collecting a set of measured points of the anatomic structure of the patient, the measured points being associated with a patient space, determining a set of matches between the set of model points and the set of measured points, determining a first plurality of weights for the set of matches, and registering the set of model points to the set of measured points based on the first plurality of weights to generate a first registration.

Abstract: A method of modeling a cyclic anatomical motion comprises receiving a pose dataset for an identified point on an interventional instrument retained within and in compliant movement with a cyclically moving patient anatomy for a plurality of time parameters. The method also includes determining a set of pose differentials for the identified point with respect to a reference point at each of the plurality of time parameters and identifying a periodic signal for the cyclic anatomical motion from the set of pose differentials.

Abstract: An apparatus may include an instrument including an elongated shaft and a shape sensor including an elongated optical fiber extending within the elongated shaft at a first radial distance from a neutral axis. The apparatus may also comprise a reference sensor disposed within the elongated shaft. The shape sensor may be fixed in a known first position relative to the reference sensor. The apparatus may also comprise a twist resistant feature disposed within the elongated shaft. The twist resistant feature may be coupled to the shape sensor to reduce twisting of the elongated optical fiber relative to the elongated shaft while permitting axial translation of the elongated optical fiber within the elongated shaft. The shape sensor may be coupled to the twist resistant feature at a known second position relative to the reference sensor.

Abstract: Methods for using registered real-time images and prior-time anatomic images during an image-guided procedure are provided herein. An exemplary method includes obtaining a three-dimensional image of a patient anatomy and a portion of a medical instrument disposed therein. The three-dimensional image includes image information characterizing a shape of the portion of the medical instrument. A processing device segments the portion of the medical instrument from the three-dimensional image. Shape data is obtained from the portion of the medical instrument while the portion is positioned within the patient anatomy, and the processing device registers the segmented shape of the portion of the medical instrument with the shape data from the portion of the medical instrument.
