摘要：
A direct 3D segmentation method is proposed to segment carotid plaques from 3D ultrasound images. A 3D level-set evolution approach was applied to refine the initial plaque surface constructed by an algorithm described in this paper. Compared with the previously described 2D slice-by-slice segmentation approach method, this direct 3D segmentation approach took into account the continuity of the plaque geometry along the longitudinal direction. Experimental results (total plaque volume (TPV) difference: 3D 4.5 +/- 9.8% vs. 2D 13.3 +/- 232; Dice similarity coefficient (DSC): 84.4 +/- 5.8 % vs. 83.7 +/- 5.4 %) suggest that the proposed 3D method outperforms the 2D slice-by-slice approach.
