摘要
用加吸收体法测量了组织模拟液Intralipid-10%的吸收系数和各向异性因子。运用漫射理论研究了点光源在无限大介质中的各向异性散射,实验结果得到(μa/D)～(1/2)的多个测量值的标准偏差小于0.6%,测量值与拟合值的残差方均根值为0.1%。标准偏差和残差的值表明了测量值的准确度。
The absorption and anisotropy coefficients of the fat emulsion Intralipid-10% were measured. An adding-absorber method was used for measurement of absorption and anisotropy coefficients of the Intralipid- 10%. Using the diffusion theory which has been extended to include anisotropy scattering for a point-source in infinite-medium geometry, the standard deviations of muhiple measurements for √μa/D are less than 0. 6% and the residuals between the measured data and the fits have rms values of O. 1%, where μa is the absorbing coefficient of the solution in our experiment and D is the diffusion coefficient of the medium. The values of the standard deviations and the residuals demonstrate the high precision of the measurements.
