Solar rotational tomography (SRT) is an obsevational technique of the solar corona that allows reconstruction of the three-dimensional (3D) distribution of some of its fundamental physical parameters. Applied to white light images, SRT allows reconstruccion of the electron density. Applied to EUV images, it allows reconstruction of both the electron density and temperature. When using full-sun images, such as SOHO/LASCO-C2 in white light, or SDO/AIA in EUV, the reconstructions are of a global nature. Tomographic results are then of great value as validation tool of MHD models of the global corona. Current computational power running modern SRT algorithms deliver results in a matter of hours, with minimal human user interaction, mainly focused in image selection. We summarize the current status of the technique and future prospects based on new instrumentation.
