Improving our understanding of the mechanisms that energize the solar wind and heat structures in the solar corona require the development of empirical methods that can determine the 3D temperature and density distribution with as much spatial and temporal resolution as possible. This poster discusses some of the solar rotational tomography (SRT) methods that will be used for 3D reconstruction of the solar corona from data obtained by the next generation of space-based missions such as the Solar and Terrestrial Relations Observatory (STEREO), Solar-B and the Solar Dynamics Observatory (SDO). In the next decade SRT will undergo rapid advancement on several frontiers of 3D image reconstruction:  1. 3D electron density reconstruction from white-light coronagraph images  2. 3D electron temperature reconstruction from EUV images  3. Fusion of data from multiple spacecraft with differing instrumentation  4. Time-dependent tomography methodsAlthough the principles described apply to many different wavelength regimes, this poster concentrates on white-light and EUV data.
