Design of Long Distance Localization and Monitoring System of Radiotherapy With Heavy Ion on HIRFL-CSR

In order to fulfill the requirement of monitoring and long distance control of patients lesion location information during the shallow and deep radiotherapy with heavy ion on the Heavy Ion Research Facility in Lanzhou-Cooler Storage Ring (HIRFL-CSR), the corresponding software and visual monitoring interface were developed, the integration of ion beam transport system and therapy equipment were completed. The embedded real-time control system was constructed by FPGA technology. The PCI bus and ADLINK’s industrial control computer of PXI 3800 were used as communication interface and host computer respectively. The algorithm of the point by point comparison motion control was selected to achieve the position control. Through the test on the spot, the system is robust and reliable, and satisfies the design requirement.
