ABSTRACT:
The accuracy of radiation therapy is enhanced with the blade collimator of the claimed invention. Particularly, this collimator includes a support device for supporting at least two sets of radiation attenuating blades in a single plane or layer. The blades are reciprocally movable within this support. Shaping of the therapy may be increased by constructing the blades to include a varying width increasing from the central blade toward the exterior blades.
