Paper Abstract

The ballistic photons have been proposed for biological-tissue characterization. These photons keep its propagation direction when they are propagated through a material. They are rapidly attenuated in accordance with the density and thickness of the medium. The penetration depth for these photons is about 9 millimeters in human tissue. This attenuation may provide information to detect an inhomogeneity in the material (a possible tumor in human tissue). In order to enhance the detection of ballistic photons, interferometric setups have been proposed. Unfortunately, these setups only allow transmission measurement at a single point. We propose a novel technique using Risley prisms for area-scan with ballistic photons.
