Abstract: 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.

Abstract: A method of modeling anatomic deformation comprises receiving a reference three dimensional model of a branched anatomical formation in a reference state. The method further comprises applying a three dimensional deformation field to the reference three dimensional model to create a deformed three dimensional model of a deformed state of the branched anatomical formation and dynamically displaying an image of the deformed three dimensional model of the deformed state of the branched anatomical formation.

Abstract: A processing system may comprise a central processing unit, a graphics processing unit, and a memory having computer readable instructions. The computer readable instructions may cause the processing system to obtain a reference tree of nodes and linkages based on a reference 3D volumetric representation of a branched anatomical formation in a reference state and obtain, by the central processing unit, a reference 3D geometric model based on the reference tree. The instructions may also cause the processing system to receive, by the graphics processing unit, a non-rigid transform for the nodes of the reference tree and determine, by the graphics processing unit, a rigid transform for the reference tree nodes based on the non-rigid transform. The instructions may also cause the processing system to transform each node into a deformed node, create a 3D deformation field, and create a deformed 3D geometric model of the branched anatomical formation.

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.
