Treatment planning for conformal stereotactic radiotherapy.
Due to three dimensional planning techniques it is possible to conform the high dose region precisely to a target volume inside the brain. Special patient fixation and positioning systems allow a high precision in repositioning of the patient thus allowing fractionated stereotactic radiotherapy. Conformation can be achieved with many different irradiation techniques for example with a linear accelerator using noncoplanar arcs or conformal static beams. Noncoplanar arc therapy with multiple isocenters and conformal static beam therapy with one isocenter are compared. In both cases the DVHs of the planning target volume and normal tissue are calculated and discussed.
