Paper Abstract

A new method of an optical inhomogeneity detection in strongly scattering media having optical properties of biological tissue Time-Resolved Diffuse Optical Tomography (TR-DOT) is described. The method is based on preliminary processing of a three-dimensional surfaces obtained from the set of time-resolved data in the Cartesian coordinate system, followed by their conformal transform into surfaces in the cylindrical coordinate system. The key feature of the method is application of Late-Arriving Photons (LAP) diffusely transmitted through turbid objects. (i) LAP of each TPSF (Time Point Spread Function) standardized for a minimum angle; (ii) the resulting normalized function approximated by straight lines; (iii) normalized function is modified with the additional factor, K; (iv) final transform to the cylindrical coordinates.
