2D Fan-beam or parallel-beam SART-TV algorithm

It seems like the ART reconstruction algorithm family can only be used in con-beam reconstruction. Our research is based on 2-D CT scan, so can you consider that transfer those algorithms into a 2D version?

Hi @GreameLee
Is it only SART-TV, or is it all of them? Most of them should work.

You mean most of ART family algorithms can work on parallel-beam? if so, what is the meaning of the ALPHA in "SART(PROJ,GEO,ALPHA,NITER)"? I thought it was the cone angle in 3D geography
AnderBiguri commented
@GreameLee nope, all the geometry is defined within the geo
parameter, except the angles, which used to be defined as alpha
before, and there is some residue in the documentation still calling them that.
