Abstract
A method includes identifying stenosed region within vessel in vascular image data and generating a revascularized model of the vessel based on the vascular image data with a lumen boundary in the stenosed region adjusted to have a same cross-sectional area as healthy sections of the vessel. The method includes determining a first pressure distribution for the revascularized model at hyperemic flow, determining a second pressure distribution for the vessel in the vascular image data, and calculating a subtracted pressure distribution by subtracting the second pressure distribution from the first pressure distribution. The method includes determining an asymptotic value for the subtracted pressure distribution and calculating a value by subtracting the asymptotic value from a pressure value obtained from the second pressure distribution at a location at a beginning of the stenosed region. The method includes normalizing the value to obtain a location independent FFR value for the stenosed region.
