Abstract:
1. A method for diagnosing disease in a patient's biological tree, the method comprising the steps of: obtaining a model biological tree; 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; identifying 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; calculating model resistance based upon at least a length of a model vessel portion and a diameter of a model stem vessel proximal to the vessel crown from the model biological tree image; calculating patient resistance based upon at least the length of the patient vessel portion and the diameter of the patient stem vessel proximal to the vessel crown from the patient's biological tree image; and comparing the calculated model resistance to the calculated patient resistance to determine the extent of vessel and/or organ disease.
