  • Transmural perfusion gradient image analysis
    Patent number: 8755575
    Abstract: A system (100) for analyzing a sequence of datasets representing sequential images of an object, a dataset associating data values with positions, the images having an image region having a first border (210) and a second border (220) associated with the object, the system comprising a ray establishing means (130) for establishing for individual images an analysis ray (232; 234; 236) connecting the first and second border of the image region, the analysis rays being in a respective position representing a substantially same position with respect to the object, a gradient establishing means (140) for establishing, for individual analysis rays, a gradient value which is representative of a rate of change in the data values across the image region and along the analysis ray from the first border to the second border. The system is well suited to locate perfusion deficits in the myocardium through the identification of transmural gradients.
