Abstract:
The numerical solution of a vector field reconstruction problem is offered. It is assumed that a field is given in a unit ball. The approximation of the solenoidal part of the vector field is constructed from ray transforms known over all the straight lines parallel to one of the coordinate planes. Good results of reconstruction of solenoidal vector fields by the numerical simulations are proposed.
Key words:
vector tomography, solenoidal field, approximation, inversion formula, ray transform, fast Fourier transform.
