摘　　要：目的:测定不同剂量放射源对Infinia Hawkeye均匀性校正的影响。方法:配制不同剂量放射源,分别进行均匀性校正测验。结果:不同剂量放射源所得均匀性校正有所不同,测定需要的时间也有较大差别。结论:选择20 kcts/s和30 kcts/s放射性源为较理想的剂量。Objective To determine the influences of the radioactive sources with different doses on Infinia Hawkeye uniformity correction.Methods The radioactive sources with different doses were prepared,and underwent uniformity calibration test respectively.Results The uniformity calibrations by different sources were not the same,and also the time expended.Conclusion The dose of 20 kcts/s or 30 kcts/s is ideal for the radioactive source.
