Abstract

In this article, we investigate V-line transforms for symmetric mm-tensor fields whose support lies inside a disk of radius RR and centered at the origin. We provide an explicit characterization of the kernel of the V-line transforms acting on a symmetric mm-tensor field and derive a new inversion formula using a decomposition result. In addition, we present a comprehensive numerical verification and validation of the inversion algorithms for these V-line transforms for vector fields and symmetric 22-tensor fields, which were recently developed in \cite{bhardwaj_2024,bhardwaj2025tensor}. The reconstruction results obtained for various phantoms demonstrate the effectiveness and robustness of the proposed numerical methods, including in the presence of noise.
