Engineering Notes
A narrow window (e.g., 80) gives high contrast for small density differences (brain CT). A wide window (e.g., 1500) is used for lung detail.
Troubleshooting
Very narrow or very wide default windows cause sub-optimal initial display. Coordinate with radiologists to configure optimal protocol-specific window presets on the modality.
