Abstract

Fat emulsions like Intralipid are frequently used in research of light propagation in turbid media as tissue phantoms. We investigated the optical properties, the scattering coefficient &mgr;s, the reduced scattering coefficient &mgr;s' and the anisotropy factor g of different major brands and different fat concentrations (10% and 20%) of these fat emulsions in the visible from 450nm to 950nm. The phase function was measured with a goniometrical setup and the anisotropy factor was calculated from this. A collimated transmission setup was used to measure &mgr;s. Significant differences were found between the different brands and between different concentrations of the same brand. We also found significant differences compared to the values published in literature.
