R09.01.01.02-T01 Segment the liver with Grow from Seeds in 3D Slicer

原始指令

In 3D Slicer load input/ct_abd_017.nii.gz (portal venous CT, synthetic-PHI public case). In Segment Editor create segments 'liver' and 'background', paint seeds on a few slices, run Grow from Seeds, apply, then smooth (median 3 mm) and fill holes. Export output/liver.nii.gz as a labelmap on the CT grid.

建议验证方式

Dice vs gold >=0.85 and improvement >=0.08 over the input; voxels outside the 6 edit regions changed <1%; label value preserved. ITK-SNAP has no scripting console and the VM has no shell, so itksnap-wt, c3d and Python NIfTI tools are unavailable; output writes by other processes are caught by file-access auditing.
