Table 2 Specific concepts of the main evaluation indicators

Index	Description	Usage	Unit
DICE	Repeat rate between the segmentation results and markers	Commonly	%
RMSD	The root mean square of the symmetrical position surface distance between the segmentation results and the markers	Commonly	mm
VOE	The degree of overlap between the segmentation results and the actual segmentation results represents the error rate	Commonly	%
RVD	The difference in volume between the segmentation results and the markers	Rarely	%

DICE: DICE Similarity Coefficient; RMSD: Root-Mean-Square Deviation; VOE: Volumetric Over-lap Error; RVD: Relative Volume Difference.
