Table 1.  Results of the analysis of tissue characteristics: specific surface area SV, characteristic length Lc and mean distance dO2¯ and standard deviation from all tissue voxels to air as well as the mean concentration of lymphocytes cl for all six Covid-19 positive samples as well as for one control sample. Colors match the distance graphs in Figure 6.
