Solar rotational tomography is an observational technique of the solar corona that allows reconstruction of the global three-dimensional distribution of some of its fundamental physical parameters, such as electron density. EUV tomography is routinely applied to data provided by spaceborne telescopes, typically covering the range of heliocentric heights 1.02-1.25 R. This range partially overlaps that of the field of view of the white light K-coronagraph (KCOR) instrument, at the High Altitude Observatory (HAO), which covers the range 1.05-3.0 R. In this work we show preliminary results of the first comparison of tomographic reconstruction of the coronal electron density based on EUV images against the reconstruction based on white light images. Results are discussed in terms of the diverse characteristics of the used data sets, as well as the different physical factors that affect each analysis.
