Claim 18:
19. A treatment method, comprising:
configuring a medical system for delivering a first treatment beam having a first energy level from an accelerator, including
delivering the first treatment beam to a beam deflector, the beam deflector including a permanent magnet and an electromagnet;

delivering the first treatment beam by the medical system from the beam deflector towards a patient that is on a patient support;
configuring the medical system for delivering a second treatment beam having a second energy level from the accelerator to the beam deflector, including
changing the first energy level to the second energy level with an energy switch communicatively coupled to the accelerator, and
adjusting a current of the electromagnet with a current control communicatively coupled to the beam deflector based on the second energy level; and

delivering the second treatment beam by the medical system towards the patient;
wherein the first treatment beam is delivered towards the patient from a first gantry angle, and the second treatment beam is delivered towards the patient from a second gantry angle.
