Calculating a fractional flow reserve

Abstract

A method for vascular assessment is disclosed. The method, in some embodiments, comprises receiving a plurality of 2-D angiographic images of a portion of a vasculature of a subject, and processing the images to produce a stenotic model over the vasculature, the stenotic model having measurements of the vasculature at one or more locations along vessels of the vasculature. The method, in some embodiments, further comprises obtaining a flow characteristic of the stenotic model, and calculating an index indicative of vascular function, based, at least in part, on the flow characteristic in the stenotic model.

The invention is claimed as follows: 
     
         1 . A computer-implemented method for assessing a vascular function of a cardiac vasculature having a stenotic segment, the method comprising calculating a flow index quantifying the vascular function of the cardiac vasculature using medical images.
