| 摘 要： | 基于光动力过程中的光分布规律,研究了半无限大组织中组织光学特性和光分布对光漂白作用效果的影响.研究发现光漂白效果与组织的散射系数和吸收系数成反比;光漂白的有效作用深度是4.5 mm,最大作用深度是33 mm.研究所得结果不仅表明通过光分布研究光漂白的特性是一种有效的方法,而且对临床上设计合理的治疗法案具有重要的参考作用...

| Abstract: | Based on the distribution of photons in tumor during photodynamic therapy, effection of photobleaching caused by optical properties of tumor and the distribution of photons is researched. It showed that effection of photobleaching is inversed to absorption coefficient and scattering coefficient. And effective depth of photobleaching is 4.5 mm,the maximum depth of photobleaching is 33 mm. The results, which has important reference value for clinic to design an optimal scheme for photodynamic therapy, showed that it is effective for studying photobleaching characteristics. |
