A simple analytic expression was developed to approximate the behavior of the data, SIGNAL(zf). The expression is:

SIGNAL = MEASUREMENT/Po = μs Lfocus f exp(-a μs zf 2 G)


The figure shows the behavior of a(g) and f(g), based on Monte Carlo simulations for a, and on integrtion of the Henyey-Greenstein scattering fucntion for f.

The behavior of f is expressed as f/fiso, i.e. normalized by the value of f for isotropic scattering, to allow plotting on the same graph.

A water-immersion lens was used, and this analysis has neglected the slight effect of the water-tissue refractive index mismatch.
