Grid Therapy for Tumors of the Head, Neck, Thorax, Abdomen, Pelvis and Extremities.

Grid therapy allows for high doses of radiation to be delivered over several spatially distinct, small regions. This permits regions of very high dose to a large tumor away from critical structures, which could be beneficial in both palliative and definitive treatments. Additionally, allowing for high doses to be delivered could pose a benefit for radioresistant histologies.
