Abstract:
We suggest an approach to the recovery of a function given in a Riemannian domain with low refraction from the ray integrals of the function. We construct an inversion algorithm with the use of the back-projection operator and the fast Fourier transform. The algorithm is investigated by numerical methods.
Keywords:
tomography, refraction, ray transform, back-projection operator, inversion formula, fast Fourier transform.
