Abstract

Dilutions of Intralipid 20% are widely used as optical phantoms for mimicking scattering properties of turbid media such as tissues. One of the frequently used methodologies for quantifying the scattering coefficient and anisotropy of Intralipid 20% is the use of single-particle Mie scattering theory, which in fact is not valid for nontenuous media. Hence, two methodologies consisting of analytical wave theory and effective medium theory, incorporating particle size distribution and concentration-dependent correlated scattering phenomena, are used to estimate the effective scattering coefficient and anisotropy of Intralipid 20% dilutions (1%-100% v/v) from 380 to 1000 nm.

摘要

20% 英脱利匹特乳剂的稀释液被广泛用作光学模型，用于模拟诸如组织等浑浊介质的散射特性。一种常用于量化20% 英脱利匹特乳剂散射系数和各向异性的方法是使用单粒子米氏散射理论，但实际上该理论对非稀薄介质并不适用。因此，采用了两种方法，即解析波动理论和有效介质理论，它们考虑了粒径分布和浓度相关的关联散射现象，用于估算380至1000 nm范围内20% 英脱利匹特乳剂稀释液（1%-100% v/v）的有效散射系数和各向异性。
