Engineering Notes
Scalar alternative to Image Position (Patient) for slice ordering. Less precise than using full 3D position vectors. Useful for display when full positional data is unavailable.
Troubleshooting
Use Image Position (Patient) over Slice Location for precise 3D operations. Slice Location is fine for simple stacking but not for 3D reconstruction.
