The imaging of inhomogeneous cylindrical fluid targets buried in a stratified medium is investigated by means of a diffraction tomography approach. The fundamental equations are briefly stated and then illustrated by a number of characteristic examples. The quality of the image is discussed when changes occur in the geometry of the target, its contrast with the embedding medium, and in the number of views. It is shown that this approach performs in an acceptable manner as long as qualitative results are sought.
