ABSTRACT:
Some embodiments include a particle source, an RF power source, an accelerator waveguide, and an imaging device. The particle source is to generate a first injector current and a second injector current, the first injector current being less than the second injector current. The RF power source is to generate first RF power at a first pulse rate and second RF power at a second pulse rate, the first pulse rate being greater than the second pulse rate. The accelerator waveguide is to accelerate a first electron beam based on the first injector current and the first RF power and to accelerate a second electron beam based on the second injector current and the second RF power, and the imaging device is to acquire an image based on the first electron beam. The second electron beam may be used to deliver treatment radiation to a patient.
