System and method for automated segmentation and analysis of the three-dimensional structure of ducts in computed tomography images

摘要

System and method to quantify, based on a CT scan, metrics and morphological characteristics of a duct irregular and heterogeneous walls and content. It is characterized by the quantization automate the steps. Image boundaries in each environment of the duct; iterating automatically segmenting triple feature extraction process (414), classifying the pixels (416) and correct classification, adjusting the existing knowledge about the properties of objects tomografiados (418); iteration stops when segmentation converges (420); the segmentation procedure is repeated with other cuts tomography (424) for volume segmentation (426). With it and the tomographic metadata models segmented duct and its axis are automatically created physico-in the coordinate system; and from these measurements they are automatically generated and morphometric descriptors characterizing the three-dimensional structure of the duct.
