Fixed geometry optical scanner for laboratory use

A research stand of diffuse optical tomography consisting of a developed laboratory optical scanner with fixed geometry and a PC computer was constructed. The analysis of usefulness of particular groups of image sensors (photodiodes p-n, photodiodes p-i-n, photomultipliers, CCD matrices and CIS matrices) and light sources (for visible and near-infrared light) for diffuse optical tomography was carried out. Optimization of the reconstruction process was performed. A number of software tools for simulation of the light propagation in tissue was developed. The innovative method, combining advantages of nodal and Monte Carlo methods, was proposed.
