The angular radiance distribution of several linear diffusers used for photodynamic therapy (PDT) was measured. The forward scattering found previously was not observed for these designs. The improved isotropy leads to a better agreement between intended treatment site and actual maximum of the fluence rate profile when the linear diffuser is used in a hollow, cylindrical organ.
测量了几种用于光动力疗法（PDT）的线性扩散器的角辐射分布。对于这些设计，未观察到先前发现的前向散射。当线性扩散器用于中空圆柱形器官时，改进的各向同性使得预期治疗部位与通量率分布的实际最大值之间的一致性更好。
