• Call: import fullseye as fs; fs.ledger.vol_window_level(vol, center, width, out_range=(0.0, 1.0)) (implementation को सीधे call करना हो तो import volgray; volgray.vol_window_level(vol, center, width, out_range=(0.0, 1.0)), registry से लेना हो तो ops3d.get("vol_window_level"))
CT window/level (HU windowing) — radiologist का रोज़ का linear remap।
> नीचे का विस्तृत विवरण मूल text में है — सारांश और headings का अनुवाद हो चुका है।
Maps the intensity window [center - width/2, center + width/2] linearly onto *out_range* (lo, hi); voxels below the window saturate at lo, voxels above at hi (clipped, by design — that is what a CT window *does*). A bone window and a soft-tissue window on the same Hounsfield volume make entirely different structures visible. HALCON analogue:
scale_image (the linear part), plus the clip.
vol : array_like, shape (D, H, W)
Input volume (coerced to float64; NaN/Inf rejected). Hounsfield units
or any other physical scale — *center* / *width* live on the same scale.
center, width : float
Window centre and full width. width must be > 0 (fail-closed).
out_range : (float, float)
Output (lo, hi) with lo < hi. Default (0.0, 1.0).
ndarray, shape (D, H, W), float64
The windowed volume, everywhere inside [lo, hi].
ValueError
Non-3-D / non-finite input, width <= 0, or a malformed *out_range*.
