Abstract
X-ray pixel beam array systems and methods for electronically shaping radiation fields and modulating radiation field intensity patterns for radiotherapy are disclosed. One exemplary pre-clinical system may include addressable electron field emitters () that are operable to emit a plurality of electron pixel beams (). Each electron pixel beam may correspond to an x-ray target () and x-ray pixel beam collimation aperture () to convert a portion of energy associated with the electron pixel beam to a corresponding x-ray pixel beam (). Further, the x-ray pixel beam array collimator () forms a one-to-one correspondence between individual electron pixel beam and its corresponding x-ray pixel beam. One exemplary clinical system may include a high-energy electron source (), an n-stage scanning system (), x-ray pixel beam targets (), and an x-ray pixel beam array collimator (). A controller () may sequentially direct electron beam pulses to predetermined x-ray pixel targets and produce an electronically controlled radiation field direction, pattern; and intensity pattern.
