• 呼叫: import fullseye as fs; fs.ledger.vol_profile_line(vol, p0, p1, n=None, spacing=None, order=1)(要直接呼叫實作,import volprobe; volprobe.vol_profile_line(vol, p0, p1, n=None, spacing=None, order=1);從台帳取用則 ops3d.get("vol_profile_line"))
• 經台帳呼叫的回傳值: fullseye.ledger.vol_profile_line(...) 只回傳宣告的 out 型別 pairs 的值(底層函式還會回傳輔助資訊)。需要被捨棄的部分時,請用 fullseye.ledger.vol_profile_line.raw(...),或直接呼叫 volprobe.vol_profile_line。

The segment between the two (z, y, x) voxel-space points (fractional coordinates allowed) is sampled at n evenly-spaced positions with spline interpolation of the given order (scipy.ndimage.map_coordinates; 1 = trilinear, the default). n defaults to one sample per unit of *index-space* length (~1 voxel-step resolution regardless of spacing).
vol : (D, H, W) array — the volume (float64, finite; fail-closed otherwise).
p0, p1 : (z, y, x) — probe start / end, inside the volume on every axis.
n : int, optional — sample count (>= 2). Default ceil(index_length) + 1.
spacing : (sz, sy, sx) or volio.VolumeMeta, optional — voxel size in mm.
order : int in [0, 5] — interpolation spline order (1 = trilinear).
(t_mm, values) : two float64 arrays of length n. t_mm[i] is the *physical* distance of sample i from p0 — the cumulative Euclidean norm of the differences of the physical sample coordinates (index * spacing), exact under anisotropic spacing; in plain voxel units when spacing is None. values[i] is the interpolated gray value.
Raises ValueError on a malformed volume, an endpoint outside the volume, coincident endpoints (p0 == p1: no probe direction), n < 2 or an invalid order / spacing.
