Aurora computed tomography is a method to reconstruct 3-dimensional structure of auroral luminosity from several monochromatic auroral images simultaneously taken at the multi-station camera network. As an evolution of this method, we suggest the Generalized-Aurora Computed Tomography (G-ACT). This method aims at retrieving energetic and spatial distributions of incident auroral electrons from several kinds of data, such as ionospheric electron density from incoherent scatter radar, cosmic radio noise absorption from imaging riometer, as well as the multiple monochromatic images. In this paper, we describe a basic concept of the G-ACT and test the feasibility of this method by numerical simulation.
