Systems and methods for generating anatomic tree structures using backward pathway growth

A system for modeling an anatomic tree structure, the system comprising:

• a display system;
• and
• a control system communicatively coupled to the display system, wherein the control system is configured to:
• receive anatomic image data comprising a plurality of graphical units;
• generate an initial segmented set of the plurality of graphical units associated with the anatomic tree structure;
• receive an indication of a first user selected graphical unit from the plurality of graphical units, the first user selected graphical unit being outside the initial segmented set of the plurality of graphical units;
• apply a cost function to determine a first sequence of the plurality of graphical units from the first user selected graphical unit outside the initial segmented set to the initial segmented set of the plurality of graphical units;
• receive an indication of a second user selected graphical unit from the plurality of graphical units, the second user selected graphical unit being selected from the first sequence of the plurality of graphical units;
• and
• apply the cost function to determine a second sequence of the plurality of graphical units from the second user selected graphical unit to the initial segmented set of the plurality of graphical units.
