A new question poped up my mind when dealing with the so called FluenceActor. As it is written in the Wiki, the option enableScatter prints out the .mhd image for scattering. I assume that Compton and Rayleigh scatter are combined here. But it should be possible to get the two scatter images separate using the command /gate/actor/DetectorFluence/separateProcessFilename. In the Wiki it says to do the following: "Set the file name for the different scatter x-rays processes that hit the detector (printf format with runId as a single parameter)" But I don't understand that! Any help would be great? Cheers, Nico </body> </html>
