Apparatus and method for determining coronary physiology

摘要

A computer-implemented method for determining fractional flow reserve (FFR) of a coronary artery and a computer system are provided. Geometry data indicative of a geometry of a coronary system comprising the coronary artery are received;a 3D model of the coronary system is generated based on the geometry data; a pressure-flow relationship through at least a portion of the model is calculated based on steady-state analyses at a plurality of flow rates; the FFR is determined, based upon a non-linear impedance network having one or more characteristics based upon the pressure-flow relationship, and a measured proximal pressure of the coronary artery.
