Regarding Grow-from-Seed Limitation:
Your dataset dimensions (2184 × 1885 × 2230 ≈ 9.2 billion voxels) exceeds the practical limit of the grow-from-seed algorithm. This is not a memory issue but an algorithmic complexity issue:
- Grow-from-seed has O(n³) to O(n⁴) complexity
- Large datasets cause extremely slow computation or crashes
Recommended Solutions:
- Downsample: Resample the volume by 2x-4x before segmentation
- Crop ROI: Use Crop Volume to focus on the region of interest
- Use Alternative Methods:
- Threshold segmentation (for bones like we did)
- Deep learning (TotalSegmentator extension)
- Level set / Region growing (with smaller seed regions)
