自1960年激光问世以来,由于激光系相干光,其单色性佳,发散角小,单位面积功率强度可以达到十分大的程度,以及某些激光能与光导纤维耦合而经纤维内窥镜传导至内脏等特点,已广被采纳作医疗实践之用。利用血卟啉衍生物——激光光动力疗法诊治 Since the advent of the laser in 1960, due to the coherent light of laser light, its monochromaticity is good, its divergence angle is small, the power intensity per unit area can reach a very large degree, and some laser energy can be coupled with an optical fiber and transmitted through a fiberscope. Features such as internal organs have been widely adopted for medical practice. Using Hematoporphyrin Derivatives - Laser Photodynamic Therapy
