    摘要: A method and an apparatus for motion visualization of a moving object in angiographic images are described. In a preferred embodiment of the method, first a mask image of the object of interest is acquired and a sequence of angiographic images of the object in different phases of motion of the object is acquired. Then, a first angiographic subtraction image and at least a second angiographic subtraction image are generated by subtracting the angiographic images from the mask image. Subsequently, a twice subtracted image is generated by subtracting the first angiographic subtraction image from the second angiographic subtraction image. In this way a double subtraction, i.e. a twice subtracted angiography is performed, to facilitate the assessment of the motion.

    摘要: A method includes identifying a plurality of different anatomical sub-regions of the cardiovascular system of a subject in image data of the subject based on a subject specific cardiovascular anatomical model, wherein the plurality of different regions corresponds to regions where calcifications occur, searching for and identifying calcifications in the sub-regions based on voxel grey value intensity values of the image data, and generating a signal indicative of one or more regions of voxels of the image data respectively corresponding to sub-regions including identified calcifications. A computing system (118) includes a processor that automatically determines a plurality of different groups of voxels of image data of a subject, wherein each group of voxels corresponds to a different sub-region of the cardiovascular system of the subject and each group of voxels corresponds to a region that includes a calcification identified in the image data.
