    • 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.
    • 一种用于分析表示对象的顺序图像的数据集序列的系统(100),将数据值与位置相关联的数据集,所述图像具有具有与所述对象相关联的第一边界(210)和第二边界(220)的图像区域 ,所述系统包括用于为个人图像建立连接图像区域的第一和第二边界的分析光线(232; 234; 236)的射线建立装置(130),所述分析光线位于表示基本相同位置的相应位置 梯度建立装置(140),用于针对各个分析光线建立梯度值,所述梯度值代表跨越图像区域的数据值的变化率,并且沿着从第一边界到分析光线 第二个边界。 该系统非常适用于通过识别透壁梯度来定位心肌中的灌注缺陷。
