摘要：
Method for quantitative flow analysis of a tree of conduits perfusing an organ from at least two bi-dimensional images, the method comprising the following steps: a) making a 3D reconstruction of at least part of the tree from said at least two bi-dimensional images； b) identifying a segment of interest within the 3D reconstruction either automatically or semi-automatically upon user input； c) making calculations based on the 3D reconstruction to determine geometrical features of the conduits such as diameters, lengths, curvatures, centrelines or the like； d) receiving indication from the user to input a multi-scale functional model of the tree to be considered for the flow analysis and to input the location of the segment of interest within such model； e) adjusting the part of the functional model related to the segment of interest using geometrical features of the 3D reconstruction； f) performing quantitative flow analysis based on the functional model so obtained. A corresponding apparatus and computer program are also disclosed.
