In this paper we present an evolutionary optimisation technique to search for full beam configurations, that is beam intensity, beam shape and especially beam orientation in three different kinds of radiation therapy. This method automatically determines exact beam angles not relaying solely on a geometrical basis but involving beam intensity profiles, thus considering the effective delivered dose. Experimental results have been carried out comparing the obtained dose distribution model with that obtained with a commercial system. As stated by physician and by simulation with the same commercial system, our tools found good solutions for some real clinical cases. [ABSTRACT FROM AUTHOR]
