Abstract
The system of proton-beam formation for proton ophthalmology has been numerically simulated using the Geant4 program package. Data on the efficiency of narrow- (“pencil”) and wide proton-beam transport are presented. It is established that the use of a wide beam transport is advantageous, since it makes a significant decrease in the background-radiation level in a proton-therapy room possible and simplifies the beam-formation system.
