| 摘 要： | 根据P3近似对半无限生物组织的空间分辨漫反射理论,研究了强吸收条件下光源附近 光辐射分布的简化表达式SP3函数.研究表明:组织吸收越强, SP3函数越能准确描述光源附近空间 分辨漫反射;应用SP3函数反演强吸收组织光学参数时,由不同起始距离的漫反射数据拟合得到的反演 结果曲线存在极值,极值附近对应的反演结果最接近实际组织光学参数.

| Abstract: | Based on P3 approximate spatially-resolved diffuse reflectance theory for semi-infinite biological tissue, the simplified expression SP3 function for highly absorbing medium close to source is studied. The research result shows that function SP3 can better describe the spatially-resolved diffuse reflectance close to source for higher absorption; the inversion of the optical parameters of highly absorbing medium with function SP3 shows the existence of extreme values of the curves fitted with diffuse reflectance data for different start distances, and the inversion results near the extreme values are the most closest to the optical parameters of real tissues. |
