Recovery of a vector field in the cylinder by its jointly known NMR images and ray transforms

In the paper we consider a problem of recovering a 3D vector field given in cylinder by means of jointly known nuclear magnetic resonance (NMR) images and ray transforms. The NRM images and 2D longitudinal and transverse ray transforms are known in every plane orthogonal to the cylinder axis. The 3D ray transforms of new type connected with a family of the parallel planes are defined. Simulation confirms the legitimacy and further perspective of the proposed approach.
