  • Patent number: 12161423
    Abstract: 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.

  • Publication number: 20240389882
    Abstract: A non-transitory machine-readable media storing instructions that, when run by one or more processors, cause the one or more processors to store a deformable model of anatomic passageways of a patient anatomy. The deformable model comprises a plurality of model passageway links connected at connection points, and each of the model passageway links includes a centerline. At each respective connection point, the corresponding passageway links include an orientation. The instructions further cause the one or more processors to modify the deformable model by modifying relative orientations of one or more model passageway links of the plurality of model passageway links. The modifying is based on one or more modeling parameters that affect a shape of the plurality of model passageway links.
