Line Scanning Beam Control Using Position and Stationary Time

The patent applies preliminary action by detecting the irradiation position and measuring the stationary time before completing the irradiation process. The irradiation position detection unit and stationary time measuring unit continuously monitor beam parameters during scanning, enabling early detection of deviations from the planned irradiation pattern. This allows the system to prevent erroneous or excessive irradiation by identifying position errors or abnormal stationary times before they result in harmful effects, thus improving reliability without requiring complex post-irradiation analysis systems.

The patent implements feedback control by using the detected irradiation position and measured stationary time to continuously adjust and verify the scanning beam control. The system compares actual irradiation parameters against predetermined standards and provides feedback to the scanning control unit, which can then correct deviations in real-time. This closed-loop feedback mechanism ensures reliable irradiation control by maintaining precise positioning and timing while using relatively simple detection and control components.

The patent applies universality by designing the irradiation position detection unit and stationary time measuring unit to serve multiple functions within the scanning control system. These units not only detect position and time parameters but also provide data for verification, control adjustment, and safety monitoring simultaneously. By making these detection units multi-functional, the system achieves high reliability through comprehensive monitoring while avoiding the need for separate dedicated components for each function, thus limiting the increase in device complexity.

The system applies self-service by enabling the irradiation position detection and stationary time measurement to automatically verify and adjust the scanning beam control without requiring external intervention. The detection units continuously monitor beam parameters and feed this information back to the scanning control unit, which autonomously corrects deviations. This self-regulating mechanism improves reliability through continuous verification while keeping the device complexity manageable by eliminating the need for complex external monitoring and control systems.

The patent applies continuity of useful action by implementing continuous monitoring of irradiation position and stationary time during the scanning beam irradiation process. The irradiation position detection unit and stationary time measuring unit operate continuously throughout irradiation, ensuring that precision verification occurs without interrupting the treatment workflow. This continuous monitoring approach maintains high manufacturing precision of irradiation control while minimizing time loss by integrating measurement functions into the ongoing irradiation process rather than requiring separate verification steps.

The system applies preliminary action by performing position detection and stationary time measurement during the irradiation process itself, rather than requiring post-irradiation verification. The continuous monitoring enables real-time precision verification, allowing the system to detect and correct deviations while the treatment is ongoing. This approach achieves high manufacturing precision without significant time loss because the verification occurs concurrently with treatment delivery rather than sequentially after completion.
