My first question aims to the possibilities of parallelization. I noticed that if I run a single projection, all 4 cores of my local computer are running at almost 100%. Is there already some intrinsic parallelization step when using the ffda and what further parallelization steps are possible to speed up the simulation for 1 projection? If it helps I use a voxelized phantom, cone beam setup, a xray spectrum histogram, integrating detector and 1000 Photons. My second question is how to save several .mha images in the output folder when simulating all 1201 projections. Still, I am using the ffda actor and with the command "/gate/actor/ffda/primaryFilename output/primary.mha" the primary image gets overwritten for each projection. How can I save different primary images for each projection? Any help is appreciated! Nico <pre class="moz-signature" cols="72">-- B.Sc.
