I want to simulate the FPD detector (Flattening Panel Detector). It is composed of CsI consisting of 2352x2944 pixels.
I just learned about Geant4 and didn’t know how to create a 2D matrix to record the information. Can you guys help me with how to do it? If or have similar examples, please let me know. I really appreciate any help you can provide.
there are different ways to do it. One method is to define a parameterised geometry to voxelise your detector. The detector will be your Sensitive Volume. Then record the information in each voxel, identified uniquely with a CopyNo. You may want to look at the doiPET advanced example.
Dear @guatelli thank you for your idea.
