ABSTRACT:
A system and method for delivering radiation that comprises a source for creating an electron beam, a system that focuses the electron beam and then deflects the beam such that the beam is swept across a first target as an arbitrary pattern. The arbitrary pattern on the first target is given an additional intensity modulation. Thereafter, a lens focuses the arbitrary pattern of electrons from the first target onto a second target.
