A numerical approach is presented for solving the hydro-magnetic radiative transfer equation in 4D, in which the action of the Kompaneets operator and synchrotron cooling are taken into account. The equation is solved using the pre-conditioned Black-White-Brown line Gauss-Seidel semi-iterative method. This alternating approach enables the use of vector and parallel machines without loss of efficiency. The method can be used to constrain and search for density-, temperature- and magnetic-field distributions with or without outflows. This is appropriate for displaying spectra of 2D accretion flows that are consistent with observations of low-mass X-ray binaries.
