Esophagus Segmentation from 3D CT Data Using Skeleton Prior-Based Graph Cut

Figure 3

Example of the breaking slice detection (at slice 𝑠=22). 𝑠 is the slice number. (a)–(d) Segmentation with 3D graph and (e)–(g) results of the 2D segmentation. Red: manual contour; green: automatic contour.

(a) 𝑠=21

(b) 𝑠=𝑏𝑠=22

(c) 𝑠=23

(d) 𝑠=24

(e) 𝑠=22(2D)

(f) 𝑠=23(2D)

(g) 𝑠=24(2D)
