astra_algorithm¶
- odl.tomo.backends.astra_setup.astra_algorithm(direction, ndim, vol_id, sino_id, proj_id, impl)[source]¶
Create an ASTRA algorithm object to run the projector.
- Parameters:
- direction{'forward', 'backward'}
For
'forward', apply the forward projection, for'backward'the backprojection.- ndim{2, 3}
Number of dimensions of the projector.
- vol_idint
Handle for the ASTRA volume data object.
- sino_idint
Handle for the ASTRA projection data object.
- proj_idint
Handle for the ASTRA projector object.
- impl{'cpu', 'cuda'}
Implementation of the projector.
- Returns:
- idint
Handle for the created ASTRA internal algorithm object.
