System and method for segmentation and automated analysis of the three-dimensional structure of ducts in computed tomography images (Machine-translation by Google Translate, not legally binding)
System and method to quantify, based on a computed tomography, the metric and morphological characteristics of a conduit of irregular shape and heterogeneous walls and content. It is characterized by automating the quantification with the following stages. Dimension in each image a duct environment; segment it automatically iterating the triple process of extraction of traits (414), classify the pixels (416) and rectify the classification, adjusting it to the existing knowledge about the properties of tomographed objects (418); the iteration stops when the segmentation converges (420); the segmentation procedure is repeated with the other sections of the tomography (424) to obtain volume segmentation (426). With it and the tomographic metadata, the models of the segmented conduit and its axis are automatically created in the physical coordinate system; and from these the measurements and morphometric descriptors that characterize the three-dimensional structure of the conduit are automatically generated.
