    摘要: A medical system comprises a flexible device configured to be positioned at least partially within an anatomical passageway of a plurality of anatomical passageways within a patient anatomy. The medical system further comprises a memory device including computer executable instructions. The computer executable instructions are for performing operations comprising determining a deformation force exerted by a section of the flexible device. The operations further comprise registering a model of a candidate anatomical passageway of the plurality of anatomical passageways to a model of the flexible device based on: a shape of the flexible device; and the deformation force exerted by the section of the flexible device.

    摘要: A system comprises one or more processors. The system further comprises memory having computer readable instructions stored thereon that, when executed by the one or more processors, cause the system to: obtain a reference tree of nodes and linkages for a reference three dimensional volumetric representation of a branched anatomical formation in a reference state; based on the reference tree, generate a reference three dimensional geometric model; based on measurements from a sensor system, detect deformation of the branched anatomical formation; based on the detected deformation, obtain a deformed tree of nodes and linkages; and generate a three dimensional deformation field that represents the detected deformation of the branched anatomical formation.
