Resumen:
We present the first results of EUV tomography based on a month-long time series of 171, 195 and 284 AA images from the EUVI instrument on both STEREO A and B.  The data were taken in April 2008 and correspond to CR2069. We show global, 3D maps of the emissivities in each band as well as the global, 3D differential emission measure.  We show differences between active regions, cavity plasma (above chromospheric filaments), and ``quiet Sun" plasma, and discuss implications for coronal heating.  We use a statistically based data rejection procedure to remove the data corresponding to optically thick lines of sight before the tomographic algorithm is run.
