Paper Abstract

We described a new method to determine tissue density using a modified interferometric scattering experiment.1 The most critical aspect of the tissue characterization problem is calibration of experimental measurements. During the calibration step, the absorption and scattering indices βa and βsc are determined as a function of concentration, for each material or tissue of interest, using a set of containers to vary travel distance D. It is assumed that linear scattering coefficient, ksc (absorption coefficient, αa), is proportional to number of scattering particles per unit volume, or particle concentration, c, in [ml/l]. Attenuation is proportional to concentration of scattering/absorption centers and sample length. The calibration method relates the fringe irradiance (power modulation in one interferometer arm) with the sample concentration under controlled conditions.
