Diffuse optical tomography with spectral constraints and wavelength optimization

Appl Opt. 2005 Apr 10;44(11):2082-93. doi: 10.1364/ao.44.002082.

Abstract

We present an algorithm that explicitly utilizes the wavelength dependence of tissue optical properties for diffuse optical tomography. We have previously shown that the method gives superior separation of absorption and scattering. Here the technique is described and tested in detail, and optimum wavelength sets for a broad range of chromophore combinations are discovered and analyzed.
