摘要
介绍手持式肿瘤γ探测仪(GDP),它遵循减少放射源至探头间的距离,增加空间分辨率,提高探测灵敏度和特异性的原理,利用GDP进行了体外探测和荷瘤动物体内探测应用,初步实验结果表明:该肿瘤探测仪用于肿瘤放射免疫导向手术是可行的。
A new device for tumor to perform radioimmunoguided surgery (RIGS) was described, The instrument was based on the inverse square law that the sensitive and specificity of the detector increase as the distance between the source and the detector shorted. The experimental results showed that the hand-held gamma detecting probe was practical to pefferm radioimmuoguided surgery for tumor in vivo.
