摘要
简述了医学辐射治疗用自动多叶光栅控制系统的设计与实现。说明其结构和工作原理,重点讨论了如何使用单片机实现对直流电机的控制,以及使用模糊控制算法实现对电机运转精度的控制。该控制系统在国产设备上运行效果良好,精度完全达到设计要求。
Structure and working principle of multi leaf collimator for radiation therapy are introduced. The control system for the collimator is discussed in detail, including the single chip computer and its interface design and the fuzzy control algorithm for high distance moving accuracy. The system has been successfully implemented in a homemade collimator.
