Abstract: A control system for fine tuning or spreading a charged particle pencil beam includes a low-inductance, low-power compensation or fine-tuning magnet assembly. The feedback loop that includes the compensation magnet assembly has a faster response rate than the feedback loop that includes the scan nozzle. The compensation or fine-tuning magnet assembly is preferably disposed upstream of the scan nozzle magnet(s) with respect to the beam path to make rapid but minor adjustments to the beam position between iterations of the scan nozzle.

Abstract: The present disclosure is directed to systems and methods for real-time control of a charged particle pencil beam system during therapeutic treatment of a patient. In an aspect, the present disclosure is directed to measuring an actual shape, an actual intensity distribution, and an actual location at isocenter of the charged particle pencil beam. The actual data is compared to model treatment data in real time to determine if a statistically significant variance occurs in which case the charged particle pencil beam can be stopped mid-treatment for correction and/or analysis.
