Control of the Distribution of the Electron Beam Dose in Radiation Therapy

Instruments and Experimental Techniques volume 45, pages 103–106 (2002)Cite this article

Abstract

A method for an active control of the dose distribution produced by an electron beam in a substance is proposed. This method is based on the effect of a magnetic field on charged particles. The results of the calculations of the dose distribution for the irradiation of water as a tissue equivalent by a beam of electrons with energies of 20–30 MeV under the exposure of a magnetic field below 2.5 T are presented. Applying a field results in a dose distribution maximum at a depth of 3–6 cm. Varying the magnetic field configuration and electron energy can modify the dose distribution profile and the maximum position. This method is promising for the use in radiation therapy.
