Method of reconstruction of a tree structure has three dimensions by labelling

摘要

To reconstruct a tree angiographic, one proceeds to the acquisition of images in two orientations substantially perpendicular to the other of a tree iva, cx to reconstruct. By an operation of the tracking of segments, it is reconstructed the coordinates of the segments of the tree. It determines the uncertainties resulting from the very small number of acquisitions carried out by sending of the hypotheses av, on the shapes be deduced from the signals recorded and satisfying these hypotheses with respect to a model. The model has the particularity of being structurally, it is - to - say to be essentially description. In this model, the structural each segment of the tree structure is characterized by a number, in a direction 49 - 54, and by the numbers, direction, and the number of segments that the preceding or following. It shows that in this way, it is possible to reconstruct the more rapidly, more simply for angiographic images.
