新型PET数据采集系统设计

Design of New PET Data Acquisition System

采用Xilinx Zynq芯片替代传统PET数据采集箱的功能。利用Vivado 2016软件设计芯片电路,通过SDK进行数据传输测试.设计点源放射性实验来模拟病人的真实情况,把采集到的数据传送到上位机处理。经验证,该系统数据传输准确性无误,传输速度提升了65 MB.s^-1,满足PET数据采集系统的设计需求。

The Xilinx Zynq chip replaces the functionality of a traditional PET data acquisition box.A test was done using Vivado 2016 software to design the chip circuit,data transmission test through SDK,design point source radioactivity experiment to simulate the real situation of the patient,and transfer the collected data to the upper computer for processing.It has been verified that the data transmission accuracy of the system is correct,and the transmission speed is improved by 65MB·s^-1,which satisfies the design requirements of the PET data acquisition system.
