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.
