| 摘 要： | 我们于1985年对我院1984年开展肝单光子发射计算机断层以来的52例肝病人进行了分析总结。结果表明,肝单光子发射断层在诊断肝内占位性病变方面比普通肝静态γ照相有许多优点。需要指出的是,肝单光予发射断层的若干优点及诊断的准确性是与物理条件的正确选择和应用密切相关的。本文根据至今积累的近100例断层经验,从技术方面介绍了影响单

| Abstract: | Some physical factors of liver SPECT were discussed such as consisting digital information selection, correction of rotation center, attenuation correction, uniformity correction and selection of rotation orientation. Good quality of tomographical imaging can be obtained if the factors mentioned above were strictly controled. |
