摘要： A method of operating a shape sensing apparatus comprises receiving shape data from a first shape sensor. The first shape sensor includes a first plurality of optical cores extending between a first section and a second section of an elongated optical fiber. The method further comprises receiving shape data from a second shape sensor. The second shape sensor includes a second plurality of optical cores extending between the first and second sections of the elongated optical fiber. The method further comprises determining a shape of the elongated optical fiber between the first and second sections by combining the shape data from the first and second shape sensors.

摘要： A method performed by a computing system comprises receiving a fluoroscopic image of a patient anatomy while a portion of a medical instrument is positioned within the patient anatomy. The fluoroscopic image has a fluoroscopic frame of reference. The portion has a sensed position in an anatomic model frame of reference. The method further comprises identifying the portion in the fluoroscopic image and identifying an extracted position of the portion in the fluoroscopic frame of reference using the identified portion in the fluoroscopic image. The method further comprises registering the fluoroscopic frame of reference to the anatomic model frame of reference based on the sensed position of the portion and the extracted position of the portion.

摘要： A medical system includes a flexible elongate instrument and a control unit. The control unit is configured to determine a force exerted by the flexible elongate instrument on tissue of a patient, determine a driving state of the flexible elongate instrument, set a force threshold based on the driving state, and provide feedback to an operator in response to the determined force being higher than the force threshold. Different driving states are associated with different force thresholds.

摘要： A non-transitory machine-readable media stores instructions that, when run by one or more processors, cause the one or more processors to store a deformable model of a patient anatomy and deform the deformable model based on a measured deformation of a branched anatomical structure of the patient anatomy. The deformable model includes a skeleton tree of nodes and linkages representing the branched anatomical structure of the patient anatomy. Each of the nodes is located at a respective bifurcation of the branched anatomical structure, and at each respective bifurcation the corresponding linkages include an orientation. The deformable model is deformed by modifying the orientations of the linkages of the branched anatomical structure.

摘要： A medical system comprises an instrument comprising a position sensor and a radiopaque fiducial. The system further comprises a tracking system to receive position data from the sensor, and a processor coupled to the instrument and the tracking system. The position data is in an instrument reference frame. The processor is configured to: receive external image data of a patient anatomy with the instrument disposed therein—the external image data is in an image reference frame; based on the position data, determine a first orientation of the instrument in the instrument reference frame; identify the radiopaque fiducial in the external image data; based on the identified radiopaque fiducial, determine a second orientation of the instrument in the image reference frame; and register the instrument reference frame to the image reference frame by comparing the first orientation in the instrument reference frame to the second orientation in the image reference frame.

摘要： A method for displaying guidance information during an image-guided surgical procedure comprises receiving, by one or more hardware processors, data from a tracking system associated with an elongate device comprising a flexible body and calculating, by the one or more hardware processors, at least one condition along a length of the flexible body based on the data. The method further comprises determining, by the one or more hardware processors, supplemental guidance information based on the at least one condition and augmenting, by the one or more hardware processors, one or more images with the supplemental guidance information to produce one or more augmented images. The method further comprises displaying the one or more augmented images on a display device at a surgeon console.
