Iam using Geant4 for Imaging Physics Application. And I have some questions and I hope to receive a convenient answer from you.
My question is the following:
I am using geant4 for imaging physics application. I have started with a simple example. I would like to get an image of an object, for example a box of Aluminium. To do so, I have to divide my Detector into 1024x1024 pixels. I did it by using replication along x axis and then along y axis but I do not know whether it is the right way to divide detector into pixels. I do not know if I can divide my detector directly into pixels without using replication. And then I have to generate a pyramidal beam whose spectrum is similar to that one of X-ray tube spectrum in order to cover the whole square surface of my detector.
After building such detector I have to calculate the energy deposition in each pixel and from this data ( energy deposition in each pixel versus x,y, and z) I think I can get the image of this object but I do not know how convert energy deposition versus x,y and z into image. Please, do not hesitate to inform me whether there is such or similar examples in geant4 or not.
I appreciate any help from you and thank you very much in advace. I am looking forward to hearing from you.
With kind regards
