| 摘 要： | 以一个内含３７ＭＢｑ／１０ｍｌ３２Ｐ胶体的玻璃圆盘作为实验模型，用ＮＥ８９００型γ相机及ＳＯ－ＰＨＹＤＳ７ＳＰＥＣＴ系统在不同条件下进行显像，结果发现轫致辐射最大光子分布在７０ｋｅｖ。γ相机以中能准直器、ＳＰＥＣＴ以高能准直器，能量范围及窗宽分别置于７０ｋｅｖ－６０％或８０ｋｅｖ－６０％，准直器与源间距离较短时显像，所获影像清晰，对比度好。动物实验显像效果满意。表明现有核医学成像仪器可用作轫致辐射显像。

| Abstract: | A circular glass-plate contained32Pcolloid 37MBq/10ml was used as the experimental model,the bremsstrahlung imaging was performed using NE8900 Gama camera and Sophy DS7 SPECT in different conditions.The results showed that the bremsstramung maximum photon was distributed about at 7Okev.Clear images can be obtained with middle-energy collimator of Gama camera and highenergy collimator of SPECT and 70kev-60% or 80kev-60%energy window Scale when the distance between collimator and Source was short.The results of animal test were also satisfactory.It is suggested that the present imaging instruments of nuclear medicine can be applied to bremsstrahlung imaging. |
