Szukana fraza: [Abstract = "In each case a sequence of about 130\-480 images of the artery cutoff planes were analyzed prior to their segmentation based on morphological image transformation. A crucial step in the staging of atherosclerotic alteration is recognition of the plaque in the CTA image. To solve this problem, statistical and linear fitting methods, including the least\-squares approximation by polynomial and spline polynomial functions, as well as the error fitting function were used."]
