设计了中国科学院近代物理研究所利用兰州重离子研究装置(HIRFL)进行浅层肿瘤临床治疗试验研究中所使用的束流诊断安全控制系统。该系统包括束流强度监测及保护、剂量测量、扫描波形监测及保护3个部分。系统基于PXI系统及LabVIEW软件,给出了该系统的各部分结构。从系统建立时的多次测试结果以及实际临床治疗试验研究时的长期运行结果来看,该束流诊断控制系统在控制辐照剂量以及安全保护方面能够满足当前重离子加速器浅层肿瘤临床治疗试验的基本要求,为试验研究的顺利进行提供了可靠的保证。
The beam current diagnosis safety control system used in clinical trial of shallow tumors was designed by Institute of Modern Physics, Chinese Academy of Sciences, using Lanzhou Heavy Ion Research Unit (HIRFL). The system includes beam intensity monitoring and protection, dose measurement, scanning waveform monitoring and protection of three parts. The system is based on PXI system and LabVIEW software, and gives the structure of each part of the system. Based on the results of multiple tests at the time of system establishment and the long-term operation results of actual clinical trial, the beam diagnostic control system can meet the current clinical trials of heavy ion accelerator shallow tumors in terms of dose control and safety protection The basic requirements for the smooth conduct of experimental research provides a reliable guarantee.
