Abstract: A radiation system includes a modulator and at least one voltage regulator. The modulator is configured to output a voltage for operation of a magnetron and an electron gun of the radiation system. The at least one voltage regulator circuit is electrically connected between the modulator and at least one of the magnetron or the electron gun, and configured to control a magnitude of the voltage output from the modulator for operation of the magnetron and the electron gun.

Abstract: Presented systems and methods enable efficient and effective radiation treatment planning and treatment, including accurate and convenient transmission of the radiation towards a tissue target. In one embodiment, a radiation system includes a particle source, a bremsstrahlung target, and a pinhole collimator. The particle source is configured to produce a particle beam (e.g., an electron beam, etc.). The bremsstrahlung target is configured to receive the particle beam and generate a photon radiation beam. The received particle beam and generated photon radiation beam can correspond to an inflected image. The inflected image can be associated with a tumor/tissue target. The pinhole collimator is configured to receive the photon radiation beam in a pattern that corresponds to the inflected image, invert the photon radiation beam pattern, and forward the results towards a tissue target.
