Fig. 2

Segmentation results and 3D reconstruction of phantom extraocular muscle by graph cut method and Mimics software. a-c show the graph cut segmentation results and muscle reconstruction without manual modification. d-f show the results of Mimics segmentation. In graph (d), the red part shows primary segmented region which included a lot of redundant regions outside the muscle as the yellow arrow indicated. e shows the modified result after observers erasing the redundant regions manually. f is the 3D visualization of the segmented and modified muscle in Mimics software
