The project of a Proton Therapy Center to be established at Botkin Hospital in Moscow is based on the simulation of basic units and systems operated at the Proton Therapy Center of the Institute of Theoretical and Experimental Physics (ITEP), Moscow. In support of the project, the proton beam formation, diagnostics and monitoring line used for the irradiation of ophthalmologic targets in Treatment Room 3 of ITEP will be modernized.
Our task was to model the arrangement of equipment in the beam formation line using a Monte Carlo code being developed under ISTC Project 3563.
The paper presents experimental and calculated results on the gradients of lateral dose distributions for different configurations of transverse and through-depth dose field formation equipment. Calculated distributions are compared with experimental data. It is shown that uniform through-depth fields can be formed with comb filters of pyramid type.
The work was in part supported by the ISTC, Grant #3563.
