Ion Beam Extraction Timing Control for Cancer Treatment Safety

The patent implements a determination unit that continuously monitors and confirms whether the ion beam on/off control timing matches the intended timing. This feedback mechanism detects deviations in real-time and triggers appropriate responses, ensuring treatment safety without requiring complex additional control systems. The determination unit compares actual beam extraction timing with planned timing, providing a straightforward feedback loop that enhances reliability while maintaining system simplicity.

The determination unit operates autonomously to monitor and confirm beam extraction timing without requiring external intervention. It self-activates when the ion beam is extracted, automatically determines whether timing matches intended timing, and triggers appropriate responses (continuation or termination of extraction). This self-service approach reduces the risk of inappropriate beam delivery while maintaining simple control architecture, as the system monitors and corrects itself without adding complex automated control layers.

The patent extracts the monitoring function into a separate, dedicated determination unit that operates independently from the main control system. This determination unit specifically handles the task of confirming beam extraction timing, separating this safety-critical function from other control operations. By taking out this specific monitoring function, the system achieves continuous safety monitoring without significantly increasing overall device complexity, as the determination unit is a focused, single-purpose component rather than a complex integrated system.
