Paper Abstract

We discuss the fabrication of optical phantoms that will serve as calibration and test standards for a diffuse optical tomographic system developed in our laboratory. For the fabrication of a phantom's matrix, two materials are compared: polyester and epoxy resins. We investigate the capacity to use either of these two resins in the fabrication of a phantom's matrix with different shapes and thicknesses. For the absorbing agent we use India ink and for diffusing agent we choose a fine titanium dioxide (TiO2) powder. We test a collimated light measurements set-up to extract: the absorption coefficient μa of a purely absorbing medium, and the scattering coefficient μs of a purely diffusing medium. We also compare the way μa and μs add in a solution of absorbing and diffusing media.
