ct_scan op• 資料種類:voxel × ctgeometry → projstack
• 呼叫: import fullseye as fs; fs.ledger.ct_forward_project(volume, geometry, device='auto')(要直接呼叫實作,import ctscan; ctscan.ct_forward_project(volume, geometry, device='auto');從台帳取用則 opstomography.get("ct_forward_project"))
• GPU:無(僅 CPU 參考實作)
沿 *geometry* 的每條射線投影體資料：離散運算子 A。
> 以下的詳細說明為原文 —— 摘要與標題已翻譯。
Rays are sampled at one voxel step, trilinearly, a sample outside the volume counting zero. For a parallel slice this is the definition of tomography.radon_transform.
:param volume: (Z, Y, X) of the geometry's vol_shape. :param geometry: dict from ct_scan_geometry. :param device: "auto", "cpu" or "cuda". :returns: (view, V, U) float array of line integrals. :raises ValueError: on a shape that disagrees with the geometry. Empty input
(volume with 0 elements) raises ValueError.
