So, summing up I would say that we successfully implemented IMRT. Today the implementation would take less time because all the components are ready and tested well. We think that chamber and film are sufficent for the physicist to fulfill his duties although it still may be very time consuming. Also Varis and Vision were integrated successfully, although Varis could be a little bit more flexible. Finally I think it would be nice to have some tools for visualization and data analysis, which gives the user some information about the technical accuracy of an IMRT treatment. So there is still room for optimization in some fields.
