Reconstruction of a function from its two spherical Radon transforms with the centers on a plane
arXiv:2404.04630
Abstract
Hyperplane is a set of non-injectivity of the spherical Radon transform (SRT) in the space of continuous functions in R^d. In this article, for the reconstruction of an unknown function f from C(R^3) (the support can be non-compact), using the spherical Radon transform over spheres centered on a plane, the injectivity of the so-called two data spherical Radon transform is considered. An inversion formula of the transform that uses the local data of the spherical integrals to reconstruct the unknown function is presented. Such inversions are the mathematical base of modern modalities of imaging, such as Thermo and photoacoustic tomography and radar imaging, and have theoretical significance in many areas of mathematics
