Figure 6 : Comparison of a 2D sonogram (upper panel) with a 3D sonogram (lower panel) obtained in the same specimen.

The 7.5 MHz linear probe was used to obtain the 2D sonogram and the 40 MHz probe was used to obtain the 3D sonogram. Transverse imaging plane in the lower panel was obtained 2.5 mm below the surface of the visceral pleura. Cross sections of B-lines have mostly oval (O) shapes. Only few linear (L), slit-like shaped B-lines can be demonstrated.
