Backward projector operation (x = A^Tb)
- class vamtoolbox.projector.Projector3DParallel.Projector3DParallelPython(target_geo, proj_geo)#
- generateOccSinogram(occ_array)#
Create sinogram containing minimum values of ‘s’ within the occlusion map
- Returns:
occ_sinogram (nd_array)
Npixels x Nangles x Nslices
- forward(target)#
Computes forward Radon transform of the target space object accounting for reduced projection contribution due to occlusion shadowing
Inputs#
target : nd_array Npixels x Npixels x Npixels array that contains the target space object
- returns:
projection (nd_array)
Npixels x Nangles x Nslices array of forward Radon transform with occlusion shadowing
- backward(projection)#
Computes inverse Radon transform of projection accounting for reduced dose deposition due to occlusion shadowing
Inputs#
projection : nd_array Npixels x Nangles x Nslices array that contains the projection space sinogram of the target
- returns:
reconstruction (nd_array)
Npixels x Npixels x Npixels array of inverse Radon transform with occlusion shadowing
- getOccShadow(i, j, angle, t, s)#
