Claim One:
1. A method of image processing to determine a blood flow characteristic, comprising: receiving patient-specific image data that includes a representation of at least a vessel and a stenosis in the vessel of a patient; estimating an outlet flow rate of the stenosis based on a cross-sectional metric at an outlet of the stenosis, a cross-sectional metric at an inlet of the stenosis, and an estimated blood flow rate or pressure at the inlet of the stenosis; estimating a fractional flow reserve (“FFR”) or resistance to flow of blood through the stenosis based on the estimated blood flow rate or pressure at the inlet of the stenosis, the estimated outlet flow rate, and a computational fluid dynamics simulation; assigning, to the estimated FFR or resistance of the vessel, one of a plurality of different pre-defined visual indicators based on an empirical model and one of the estimated outlet flow rate or the estimated FFR or resistance; and generating a display indicative of the visual indicators assigned to the estimated FFR or resistance.
