摘　　要：为实现MOSFET(Metallic oxide semicendctor field effect tramsistor)剂量测量系统与核通高剂量率后装放射治疗机(microSelectron-HDR)辐射与测量的同步,设计了一个基于接口电路的触发系统,并在Qt平台下开发了相应的监测和采集触发程序。经测试证明,连接控制系统运行稳定,工作可靠。所采用的串口检测技术也可以扩展到其他医疗设备的连接应用上。dose system, a trigger system based on interface circuit was designed and corresponding monitor and trigger program were developed on Qt platform. This interface and control system was tested and showed stable operate and reliable work. This adopted serial port detect technique may expand to trigger application of other medical devices.
