Illustration of the different steps of the interactive segmentation tool for the peritoneum. a A curve is generated to link all control points using 2D B-spline fitting technique. b Control points are copied directly from previous segmented slice. c A yellow rectangle is generated to refine the position of control points along the X- or Y-axis. d A set of consecutive control points can be modified at the same time by defining two fixed points (marked by red). e The position of a selected control points are moved to new position using the method of d. f A 3D mesh is created corresponding to the peritoneum after segmentation of at least four slices
