Abstract
Presented systems and methods enable efficient and effective radiation planning and treatment, including accurate and convenient transmission of the radiation towards a tissue target. In one embodiment, a radiation system includes an electron gun, a bend magnet, a scan control component, and an electron beam entry angle control component. The electron gun is configured to generate electrons. The linear accelerator is configured to accelerate the electrons in an electron beam. The bend magnet is configured to bend the path of the electron beam. The scan control component controls movement of the electron beam in a scan pattern. The electron beam entry angle control component is configured to control the entry angle of the electron beam.
