LION.operators.ct

Computed tomography: the geometry (the CT operator’s parameters), the projection operator, noise and HU conversions, and CT reconstructions.

Modules

CTProjectionOp(geometry[, backend, device])	The CT projection operator of geometry (tomosipo) and its adjoint, the backprojection, on device (LION's if None).
ct_geometry
ct_utils
fdk(sino, op[, clip, differentiable])	FDK (fan or cone beam) or FBP (parallel beam) reconstruction of sino: batched (B, C, angles, detectors) or one (C, angles, detectors) sample, the result laid out the same way.
sirt(sino, op, num_iterations[, ...])	Compute SIRT reconstructions on a batched input.
tv_min(sino, op, lam[, num_iterations, L, ...])	Compute TV-minimization reconstructions on a batched input.
