Method for evaluation of three-dimensional image dataset, involves segmenting esophagus in region of interest, where two outer contours of esophagus are separated in different image layers

摘要

The method involves segmenting esophagus (1) in a region of interest, where two outer contours of the esophagus are separated in different image layers (2). Longitudinally successive pairs are formed (8) by the outer contours. Other outer contours, in the intermediate image layers, are determined by inverse Fourier transformation.
