The use of dynamic movements on linear accelerators during irradiation have found a revised interest lately due to the integration of computers to control the linear accelerator. An example of this is the generation of fields that resemble ordinary wedge fields. These fields are produced by moving one of the collimator blocks during irradiation, i. e. dynamic wedges.A pencil beam based system with the possibility of modelling dynamically modulated dose distributions from collimator movement specifications has extensively been investigated. Special interest has been focused on depth doses, profiles and output factors which have been generated by dynamic wedge fields. The data from the treatment planning system has been verified with measurements in water on a Varian 4 MV linear accelerator.The results indicate that calculations accurately predicts the outcome from dynamic wedges without any additional measurements than those used for characterisation of static open beams.
