Feasibility examples of lymph node segmentation in X-ray CT data. (a) One 2-D slice from 3-D CT image. (b) Manual segmentation of lymph node boundaries. (c) Segmentation failure resulting from the conventional graph-cut method. (d) Simultaneous region–surface segmentation of the lymph node (blue) and surrounding tissues (green and yellow) using our new approach showing excellent segmentation performance. The improvement is indicated by the arrow.
