Abstract
In at least one embodiment, a method for determining the resistance of a flow within at least a portion of a vessel is provided, with the method comprising the steps of obtaining a biological tree image showing a structure of at least part of a biological tree, identifying a length of a vessel portion and a diameter of a stem vessel proximal to the vessel crown from the biological tree image, and calculating resistance based upon at least the length of a vessel portion and a diameter of a stem vessel proximal to the vessel crown. In another embodiment, a method for determining vessel volume is provided, with the method comprising the steps of obtaining a biological tree image showing a structure of at least part of a biological tree, identifying a diameter of a stem segment and a length of a stem segment from the biological tree image, and calculating cumulative crown volume based upon at least the diameter of the stem segment and the length of the stem segment.
