Abstract: 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 patient's vasculature and a measured distribution of a contrast agent delivered through the patient's 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 patient's 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.

Abstract: A method is for providing a medical image of a patient, acquired via a computed tomography apparatus. An embodiment of the method includes acquiring first projection data of a first measurement region; acquiring second projection data of a second measurement region; registering a reference image to the at least one respiration-correlated image of the patient, wherein the reference image corresponds to the at least one functional image of the patient or is reconstructed under a second reconstruction rule from the second projection data, to produce a deformation model; applying the deformation model to the at least one functional image of the patient; combining the at least one functional image of the patient, deformed by the applying of the deformation model, with the at least one respiration-correlated image of the patient, to produce the medical image of the patient; and providing the medical image of the patient.

Abstract: Automatic characterization of the Agatston score from coronary computed tomography (CT) is provided. In various embodiments, a plurality of coronary computed tomography images are segmented into a plurality of segments corresponding to features of coronary anatomy. A plurality of calcium candidates are extracted from the plurality of coronary computed tomography images by thresholding. Coronary calcification is located in the coronary computed tomography images by applying a trained classifier to the plurality of calcium candidates. An Agatson score is computed from the located calcification.

Abstract: According to one or more embodiments, a method, a computer program product, and a computer system for detecting and characterizing aortic pathologies are provided. The method may include receiving, by a computer, one or more tomograph scan images corresponding to a patient's aorta. The one or more received tomograph scan images may be analyzed by the computer for one or more image features associated with one or more aortic pathologies, such as aortic dissection or an aortic aneurysm. One or more image features associated with the one or more aortic pathologies may be identified in the one or more analyzed tomograph scan images, which may allow the determination of an aortic pathology associated with the patient's aorta based on the identification of the image features. A portion of the aorta and one or more branch arteries corresponding to the determined aortic pathology may then be identified.

Abstract: Disclosed are a computing system and method for identifying and visualizing a thrombosis. The method includes: registering an acquired computer tomography (CT) image of an examinee and a computer tomography angiography (CTA) image-based average standard model to each other; identifying a candidate blood vessel region from the CT image based on the results of the registration; acquiring a volume, selected by applying a threshold value for the brightness of the CT image to the candidate blood vessel region, as a first thrombosis candidate region; acquiring at least part of the first thrombosis candidate region as a second thrombosis candidate region based on the size information of the first thrombosis candidate region; and visualizing the second thrombosis candidate region by assigning a visual effect, adapted to distinguish the second thrombosis candidate region from the remaining portion of the CT image, to the second thrombosis candidate region.
