Up: Guitton: Operator/data aliasing
Previous: Results with the frequency
The inversion of the PRT can be done quickly in the Fourier domain using
a least-squares inverse. Employing an antialiasing operator helps
focus more precisely in the radon domain.
I demonstrated that data aliasing effects can be eliminated using
a sparse solver in the time or frequency domain. The frequency domain
solution, however, may need to be applied in patches.
