1. A method for diagnosing and treating disease in a patient'"'"'s biological tree, the method comprising the steps of:
- using a processor to produce an image showing a vasculature of at least part of a patient'"'"'s biological tree, wherein the processor is operably connected to a storage medium capable of receiving and storing the image;
calculating patient resistance based upon at least a length of a patient vessel portion and a diameter of a patient stem vessel proximal to the vessel crown from the patient'"'"'s biological tree image;
obtaining a model biological tree image and comparing the calculated patient resistance to a calculated model resistance calculated from the model biological tree image to determine the extent of vessel and/or organ disease; and
treating the patient based on the determined extent of vessel and/or organ disease.

Abstract
Methods are provided for determining flow resistance within at least a portion of a vessel, whereby at least a partial biological tree image is obtained and resistance is calculated therefrom based upon at least the length of a defined vessel portion and a diameter of a stem vessel at a location proximal to a vessel crown. Methods are also provided for determining vessel volume, whereby at least a partial biological tree image is obtained and cumulative crown volume is calculated based on at least the diameter and length of the stem segment.

11. A method for diagnosing and treating disease in a patient'"'"'s biological tree, the method comprising the steps of:
-
using a processor to produce an image showing a vasculature of at least part of a patient'"'"'s biological tree, wherein the processor is operably connected to a storage medium capable of receiving and storing the image; calculating patient cumulative crown volume based upon at least a diameter of a patient stem segment and a length of a patient stem segment from the patient'"'"'s biological tree image; obtaining a model biological tree image and comparing the calculated patient cumulative crown volume to a calculated model cumulative crown volume calculated from the model biological tree image to determine the extent of vessel and/or organ disease; and treating the patient if the determined extent of the vessel and/or organ disease indicates an inefficiency of the vasculature. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A system for diagnosing disease in a patient'"'"'s biological tree, the system comprising:
-
a processor; a storage medium operably connected to the processor, the storage medium capable of receiving and storing data relative of measurements from a vasculature of a vessel; wherein the processor is operable to; produce an image showing a vasculature of at least part of a patient'"'"'s biological tree, the image to be received and stored in the storage medium; calculate patient resistance based upon at least a length of a patient vessel portion and a diameter of a patient stem vessel proximal to the vessel crown from the patient'"'"'s biological tree image; and obtain a model biological tree image and compare the calculated patient resistance to a calculated model resistance calculated from the model biological tree image to determine the extent of vessel and/or organ disease.
