Abstract: Computer-implemented methods and systems are provided for quantitative hemodynamic flow analysis, which involves retrieving patient specific image data. A 3D reconstruction of a vessel of interest can be created from the patient specific image data. Geometric information can be extracted from the 3D reconstruction. A lesion position can be determined. Patient specific data can be obtained. Hemodynamic results can be calculated based on the geometric information, the lesion position and the patient specific data.

Abstract: Computer-implemented methods and systems are provided for charactering a property of microvascular tissue that is supplied with blood via a coronary artery under investigation, which involve obtaining an x-ray angiographic image sequence of the coronary artery under investigation acquired while contrast agent flows into and through the coronary artery under investigation. The angiographic image sequence is used to determine a volumetric flow rate for flow through the coronary artery under investigation, which is used to determine an index that represents a property of the microvascular tissue that is supplied with blood via the coronary artery under investigation.

Abstract: Methods for correlating intraluminal data with x-ray image data involve providing x-ray image data of a tubular organ, providing intraluminal data of the tubular organ, synchronizing the x-ray image data with the intraluminal data based on a cardiac cycle extracted from an available input signal and/or the x-ray image data and/or the intraluminal data to match x-ray image data with intraluminal data in a specific cardiac phase, and co-registering x-ray image data with intraluminal data by creating a cumulative image at the specific cardiac phase which reconstructs the path followed by an intraluminal wire used for acquiring the intraluminal data to link the intraluminal data to spatial locations of the path followed by the wire within the x-ray image. A corresponding system and computer program are also disclosed. The method and systems can be controlled by one or more computer systems configured with specific executable instructions.

Abstract: A method for providing guidance in Cardiac Resynchronization Therapy (CRT) comprising: a) providing image data sets of the heart of a patient; b) creating a three-dimensional (3D) anatomical model of the cardiac structures; c) calculating myocardium infarct scar distribution; d) calculating heart mechanical activation data; e) superimposing the scar distribution and the mechanical activation data on the 3D anatomical model to obtain a 3D roadmap model including anatomical geometry and mechanical activation data. A corresponding device and computer program are also disclosed.
