    摘要： A method of deriving blood flow parameters from a moving three-dimensional (3D) model of a blood vessel includes determining a reference vascular cross-sectional plane through a location of a lumen in a moving 3D model of the blood vessel at one time within the model, determining a plurality of target vascular cross-sectional planes at multiple times via temporal tracking of the reference plane based on a displacement field, determining a plurality of contours based on an intersection of the target vascular cross-sectional planes with the moving 3D vessel model at multiple times within the model, and determining a blood flow parameter of the vessel from intersections of each contour of a given one of the times with a phase contrast magnetic resonance (PC-MRI) image of the blood vessel from the corresponding time.

    摘要： In a method and system for automated evaluation of an image data set of a subject, first features are extracted from the image data set that are associated with the subject. An interdependency between the image data set of the subject and a reference system that corresponds to the image data set is determined, by the extracted first features being set in relation to corresponding second features in the reference system. Method steps relating to image evaluation that are predefined at the reference system, are adapted to the image data set using the determined interdependency. The image data set by executing the adapted method steps on the image data set. The evaluated image data set is stored in a storage medium and/or the evaluated image data set is visually presented.

    摘要： A system dynamically improves quality of medical images using at least one processing device including an image analyzer, a correction processor and a message generator. The image analyzer automatically parses and analyzes data representing an image of a particular anatomical feature of a patient acquired by a medical image acquisition device to identify defects in the image by examining the data representing the image for predetermined patterns associated with image defects. The correction processor uses a predetermined information map associating image defects with corresponding corrective image acquisition parameters to determine corrected image acquisition parameters for use in re-acquiring an image using the image acquisition device in response to an identified defect. The message generator generates a message for presentation to a user indicating an identified defect and suggesting use of the corrected image acquisition parameters for re-acquiring an image.
