% IRADON_GPU_WRAPPER back projector that allows to split the full volume
|
||
% into smaller pieces, tomography projector is based on ASTRA toolbox can be used
|
||
% either for data in RAM or on GPU (automatically decided from class of volData)
|

%
|
||
% vol = iradon_gpu_wrapper(sinogram, cfg, vectors)
|

%
|
||
% Inputs:
|
||
% **projData - array Nlayers x width_sinogram x Nangles of back-projected data
|
||
% **cfg - config structure generated by ASTRA_initialize
|
||
% **vectors - orientation of projections generated by ASTRA_initialize
|
||
% Outputs:
|
||
% ++vol - backprojected volume
