Patent number: 10258303Abstract: The invention relates to an apparatus for determining a fractional flow reserve (FFR) value of the coronary artery system of a living being (3). A fractional flow reserve value determination unit (13) determines the FFR value by using an FFR value determination algorithm that is adapted to determine the FFR value based on a boundary condition and a provided representation of the coronary artery system, wherein the boundary condition is specific for the living being and determined by a boundary condition determination unit (12). Since the boundary condition determination unit determines a boundary condition, which is specific for the living being, and since the fractional flow reserve value determination unit not only uses the provided representation of the coronary artery system, but also the living being specific boundary condition for determining the FFR value, the accuracy of the FFR value, which is non-invasively determined, can be improved.Type: GrantFiled: June 24, 2015Date of Patent: April 16, 2019Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Michael Grass, Yechiel Lamash, Liran Goshen, Holger Schmitt, Mordechay Pinchas Freiman, Hannes Nickisch, Sven Prevrhal
