[A program for optimizing radiation beam parameters in radiotherapy (author's transl)].

Abstract

A very large-use optimization technique for radiation treatment planning is presented. Very few input data are sufficient to enable the program to work out an optimized dose distribution; optimization is obtained by modifying the intersection point of beams and the size, the wedge and the time of each beam. The technique may be extended to moving beam teletherapy. A memorized collection of typical geometric arrangements allows a good saving in operator's time especially during data preparation.
