3D PLANNING FOR CFRT INCLUDING IMRT
It would be a mistake to imagine that the only way to improve CFRT is to implement intensity modulation. IMRT is required when the shape of the target volume demands it or the juxtaposition of target and OARs makes it impossible to obtain an acceptable plan by other methods. Many treatments will continue to require beams which are not intensity modulated and for this reason we shall discuss such situations and what can be done to optimize them. This will drive into focus even better the specific role of intensity modulation.
