Dear, Geant4 users and experts,
Hello. I am a beginner of Geant4.
I am studying about mechanism of nanoparticle-aided radiotherapy.
In this study, I would like to distribute gold nanoparticles (e.g., diameter: 50 nm, type: sphere) isotropically in a sphere volume (i.e., specifically, if we define r_a and r_b as inner and outer radius of sphere volume, respectively, I would like to distribute the nanoparticles in the volume between r_a and r_b)
I think, if I define one gold nanoparticle, then, I would distribute the particles using “G4PVReplica” class. However, due to a number of particles (e.g., 1.4 X 10^5 GNPs), it might be a very time-consuming and unproductive work.
Thus, I would like to ask whether there are any other ways to distribute the nanoparticles without using the “Replica” class. If it is, could you share your knowledge ?
Thank you for your reading.^^
