The most direct representation of the measurements provided by the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) is a set of Fourier components of the X-ray radiation sam- pled at discrete points of the spatial frequency plane, the so called visibilities. Here we review methods for the reconstruction of X-ray and elec- tron maps using RHESSI visibilities and show how the electron maps can be utilized to infer information on the physical properties of the acceleration region during flaring events.

Abstract
The most direct representation of the measurements provided by the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) is a set of Fourier components of the X-ray radiation sam- pled at discrete points of the spatial frequency plane, the so called visibilities. Here we review methods for the reconstruction of X-ray and elec- tron maps using RHESSI visibilities and show how the electron maps can be utilized to infer information on the physical properties of the acceleration region during flaring events.
