摘要：
Systems and methods are disclosed for assessing the severity of plaque and/or stenotic lesions using contrast distribution predictions and measurements. One method includes: receiving patient-specific images of a patients vasculature and a measured distribution of a contrast agent delivered through the patients vasculature associating the measured distribution of the contrast agent with a patient-specific anatomic model of the patients vasculature defining physiological and boundary conditions of a blood flow model of the patients blood flow and pressure simulating the distribution of the contrast agent through the patient-specific anatomic model comparing the measured distribution of the contrast agent and the simulated distribution of the contrast agent through the patient-specific anatomic model to determine whether a similarity condition is satisfied and updating the defined physiological and boundary conditions and re-simulating distribution of the contrast agent through the one or more points of the patient-specific anatomic model until the similarity condition is satisfied.
