This paper tackles two issues in laser imaging. The first one concerns an upstream mathematical question. We provide some link between transmission tomography and reflective tomography on a canonical case. It reinforces the credibility of transmission algorithms in reflective imaging. The second one concerns a downstream visualization issue. The Maximum Intensity Projection (MIP) is shown to be well suited; the FDK algorithm and the MIP are combined in a home-made software whose functionnalities include real-time displacements in the virtualized scene. The relevancy of this approach is shown on a real laser example.
