Criteria

5

Strongly agree

Minor edits which are not clinically important, or no edits are required. Can use the contours in the clinic without any edits

Minor edits (peripheral portal veinous branches) are required, and the time required to recontour is minimal

3

Neither agree nor disagree

Major edits (Major vessels (hepatic veins, right/left/main portal, and segmental portal vein branches) boundaries and anatomical boundaries (intersegmental fissure and gall bladder fossa) need to be corrected) but time required to recontour is minimal

2

Disagree

Major edits are required, and the time required to edit the contour is extraordinarily long

1

Strongly disagree

Segmentations are unusable
