摘　　要：采用计算机辅助的光子计数装置实时测量了ＰＤＴ过程中实验肿瘤Ｓ１80内透射光密度的变化，结果观察到透射光密度呈下降趋势，应用ＨｐＤ的肿瘤内光密度变化与无ＨｐＤ肿瘤内光密度变化相比，有显著性差异（Ｐ＜０．０１）。A computerized photon counting method was developed for surveillance of changes of intratissular spec-tral transmittance density in S180 tumor during PDT.A statistical significant difference was found between theHpD group and non-HpD group(P<0.01).The results indicate that laser penetrance is tending to be de-creased while laser fiber is punctured in a tissue.
