Measurements of Absorption and Anisotropy Coefficients of the Fat Emulsion Intralipid-10%

We report measurements of absorption and anisotropy coefficients of the fat emulsion Intralipid-10%. An addingabsorber method is used for measurement of absorption and anisotropy coefficients of the Intralipid-10%. Using the diffusion theory which has been extended to include anisotropy scat geometry, we found that the standard deviations of multiple measurements for√μα/D are less than 0.6% and the residuals between the measured data and the fits have rms values of 0.1%, where μα 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.
