1. A method for analyzing an anatomical structure of a patient, the method comprising:
receiving volumetric scan data representative of three-dimensional features of the anatomical structure, the features comprising branching points, pathways connecting the branching points, and three-dimensional location data of the branching points and the pathways;
mapping the features of the anatomical structure to a node tree diagram, the node tree diagram representing the anatomical structure and having:
a plurality of nodes, each of the plurality of nodes representing a branching point in the anatomical structure and the plurality of nodes comprising:
a first root node representing a root branching point in the anatomical structure, and
one or more additional nodes representing one or more additional branching points in the anatomical structure,
one or more branches, each of the one or more branches connecting two of the plurality of nodes, each of the one or more branches representing a pathway between two branching points in the anatomical structure, wherein the plurality of nodes and the one or more branches are arranged with the first root node being located centrally and the one or more additional nodes being positioned a distance from the first root node, the position of the additional nodes being based on at least one of:
the number of branching points between each additional branching point and the root branching point, and
the generational relationship between the additional branching point to the root branching point based on a standard anatomical structural model; and
a series of concentric orbit rings surrounding the first root node, wherein the series of orbit rings represents one or more anatomical parameters within the anatomical structure and each of the additional nodes is located on one of the concentric orbit rings in the series of concentric orbit rings; and
generating display data, the display data representative of the node tree diagram.
