Off-target radiation delivery is a significant issue in radiosurgery. Provided herein are novel radiosurgury methods and hardware that greatly increase the number of different potential firing positions/angles from which beams can be delivered to a target. These inventions enable sharper dosage profiles which spare surrounding healthy tissues from supra-optimal radiation. In one aspect, the invention encompasses methods and devices which move the patient's head so that various beam angles are enabled. In another aspect, the invention encompasses radiosurgery systems which can emit higher numbers of beams and/or wherein the independent movement of individual beams emitters is enabled. In yet another aspect, the invention encompasses a system for image-guided delivery of beams to a patient's head, wherein the patient moves their head in a predetermined and simple movement pattern to enable delivery higher numbers of potential beams. |
