-------------------------------------------------------------------------------------
1) AstraReconCpu(savu.plugins.reconstructions.astra_recons.astra_recon_cpu)
Wrapper around the Astra toolbox for cpu reconstruction
1) init_vol : None
Dataset to use as volume initialiser (doesn't currently work with preview).
2) log : True
Take the log of the data before reconstruction (True or False).
3) algorithm : FBP
Reconstruction type (FBP|SIRT|SART|ART|CGLS|FP|BP|).
4) n_iterations : 1
Number of Iterations - only valid for iterative algorithms.
5) preview : []
A slice list of required frames.
6) centre_of_rotation : 0.0
Centre of rotation to use for the reconstruction.
7) in_datasets : []
Create a list of the dataset(s) to process.
8) ratio : 0.95
Ratio of the masks diameter in pixels to the smallest edge size along given axis.
9) out_datasets : []
Create a list of the dataset(s) to create.
10) centre_pad : False
Pad the sinogram to centre it in order to fill the reconstructed volume ROI for
asthetic purposes - only available for selected algorithms and will be ignored if
unavailable (warning: This will increase the size of the data and the time to
compute the reconstruction.
11) outer_pad : False
Pad the sinogram to fill the reconstructed volume for asthetic purposes - only
available for selected algorithms and if centre_pad is True (warning: This will
significantly increase the size of the data and the time to compute the
reconstruction).
12) force_zero : [None, None]
Set any values in the reconstructed image outside of this range to zero.
13) projector : line
Set astra projector (line|strip|linear).
