This work aims to present a flexible computational model for the calculation of the lateral deflection of a pencil proton beam, and the preliminary results of its implementation in a Treatment Planning System (TPS) instead of the currently used Double Gaussian approximation (DGA) in water. First evidences show that the model has better accuracy with fast computation time in water; it is reliable for any depth and for every kind of media and mixture, since energy loss effects by the primary process are fully taken into account.

Abstract

This work aims to present a flexible computational model for the calculation of the lateral deflection of a pencil proton beam, and the preliminary results of its implementation in a Treatment Planning System (TPS) instead of the currently used Double Gaussian approximation (DGA) in water. First evidences show that the model has better accuracy with fast computation time in water; it is reliable for any depth and for every kind of media and mixture, since energy loss effects by the primary process are fully taken into account.
