Embodiment Construction

[0027] Reference will now be made in detail to the exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0028] As described above, a new generation of non-invasive tests has been developed to assess blood flow properties. These noninvasive tests use patient imaging, such as CT, to determine a patient-specific geometric model of the vessel that can be used to computationally simulate blood flow using computational fluid dynamics (CFD) along with appropriate physiological boundary conditions and parameters. Examples of these patient-specific boundary condition inputs include the patient's blood pressure, blood viscosity, and the expected demand for blood by the supplied tissue (derived from scaling laws and estimates of supplied tissue mass from patient imaging).

Abstract

Systems and methods are disclosed for predicting coronary plaque vulnerability, using a computer system. One method includes acquiring anatomical image data of at least part of the patient vascular system; performing, using a processor, one or more image characteristics analysis, geometrical analysis, computational fluid dynamics analysis, and structural mechanics analysis on the anatomical image data; predicting, using the processor, a coronary plaque vulnerability present in the patient's vascular system, wherein predicting the coronary plaque vulnerability includes calculating an adverse plaque characteristic based on results of the one or more of image characteristics analysis, geometrical analysis, computational fluid dynamics analysis, and structural mechanics analysis of the anatomical image data; and reporting, using the processor, the calculated adverse plaque characteristic.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to U.S. Patent Application No. 14 / 254,481, filed April 16, 2014, which claims priority to U.S. Provisional Application No. 61 / 917,639, filed December 18, 2013, Each of said US Patent Application and US Provisional Application is incorporated herein by reference in its entirety. technical field [0003] Various embodiments of the present disclosure relate generally to medical imaging and related methods. More specifically, certain embodiments of the present disclosure relate to systems and methods for predicting coronary artery plaque vulnerability from patient-specific anatomical image data. Background technique [0004] Coronary heart disease can produce coronary artery disease, such as stenosis (abnormal narrowing of a blood vessel), in the blood vessels that supply blood to the heart. As a result, blood flow to the heart may be restricted. Patients with coronary hea...
