稳定性元素示踪及X射线荧光分析方法具有价廉、无放射性污染、损伤少等优点,但因受辐照剂量及灵敏度的限制,发展比较缓慢。为了探讨建立免疫X荧光分析,进而发展建立在放射性核素光子源、X射线荧光分析及单色X荧光成象基础上的核医学新技术的可能性,应用CT测定了KI系列稀释溶液,估算了其对碘的检测阈,讨论了改进方法及可行性。 Stability elemental tracing and X-ray fluorescence analysis have the advantages of low cost, no radioactive contamination and less damage. However, due to the limitation of irradiation dosage and sensitivity, the development is relatively slow. In order to explore the possibility of establishing an immunofluorescence X-ray analysis and further developing new nuclear medicine based on radionuclide photon sources, X-ray fluorescence analysis and monochromatic X-ray fluorescence imaging, the KI serial dilutions were determined by CT and estimated The threshold of its detection of iodine, discussed the improved methods and feasibility.
