Claim:
1. A system comprising: a radiation source for generating a radiation beam comprising high-energy photons for both imaging and treatment of tumorous tissue in a patient, the radiation source including a charged particle accelerator that generates charged particles having energies of less than 6 megavolts (MV), a low Z target to receive the charged particles and generate the high-energy photons of preferred lower energy content distributions in the radiation beam, and a collimator to shape the radiation beam; an imaging device with a high detective quantum efficiency (DQE (0)>0.04) to define a shape and a distribution of a beam illuminated target region of the tumorous tissue in the patient; and a controller to determine a location and modulate a dose for treatment of the tumorous tissue based on the imaging device defined target region and to control the collimator to establish a shape and an intensity distribution of the radiation beam delivered to the target region.
