Paper Abstract

The goal of this work was to develop phantoms that match the refractive indices and absorption coefficients between 0.15 and 2.0 THz of the freshly excised tissues commonly found in breast tumors. Since a breast cancer tumor can contain fibrous and fatty tissues alongside the cancerous tissues, a phantom had to be developed for each. In order to match the desired properties of the tissues, oil in water emulsions were solidified using the proven phantom component TX151. The properties of each potential phantom were verified through THz time-domain spectroscopy on a TPS Spectra 3000. Using this method, phantoms for fibrous and cancerous tissue were successfully developed while a commercially available material was found which matched the optical properties of fatty tissue.
