重离子治癌电源调节器的嵌入式系统

Embedded System for Power Supply Adjustor in Radiotherapy with Heavy Ion

为满足HITFiL重离子治癌装置中对扫描铁电源精确控制的需求,基于EDA技术构建了嵌入式实时控制系统,采用高级RISC微处理器(ARM)+现场可编程门阵列(FPGA)+DA/AD技术实现对磁铁电源系统数字调节器的设计。经现场测试,本套系统运行稳定可靠,达到了设计要求,为今后重离子治癌专用装置的建设应用提供了可靠的技术保障。

In order to meet the requirement of exact control for scanning magnet power supply in the device for HITFiL radiotherapy with heavy ion, a kind of digital adjustor for magnet power supply system based on EDA technology is designed. This digital adjustor is completed by using ARM, FPGA and DA / AD technology. Through the test on the spot, the whole system was robust and reliable, satisfied the design requirement, and provided a reliable technique support for the construction and application of radiotherapy with heavy ion equipment.
