Reduction of Treatment Time in IMRT Step and Shoot Irradiations by Means of a Changed Fractionation Scheme

  • Karl-Heinz Grosser
Conference paper

Abstract

In the summer 1998 we started IMRT treatments with the step and shoot approach, using KONRAD inverse treatment planning system and a sequencer tool that has been developed at DKFZ [1], Compared to conventional multiple field irradiation techniques the treatment time is longer in IMRT step and shoot treatments. Using a SIEMENS accelerator and a SIEMENS MLC the treatment time is in complex cases up to 50 minutes. Therefore the number of patients per day who can be treated is restricted to a small number.
