The magnetically dominated solar corona is structured in the form of loops or flux tubes. To observe thisstructure during minimum solar activity epochs (or in the quiescent corona) is a difficult task because densityand temperature inhomogeneities between loops and their surroundings are relatively low, making them noteasily distinguishable in EUV images. Differential emission measure tomography, combined with a globalpotential model of the coronal magnetic field (DEMT-PFSS), allows us to characterize physical parameters ofthe coronal plasma along reconstructed loops. In this work, we tomographically reconstruct Carrington Rotation(CR) 2082 that ocurred at the minimum between Solar Cycles 23 and 24 and we statistically analyze thethermodynamic properties of coronal loops. These results are compared with the 1D model, Hydrodynamicsand Radiation Code (HYDRAD), for constant and impulsive heating regimes.
