  • Abstract
    This work describes a multi-source computed tomography. It showed to be a feasible tool to study multiphase systems. In this CT scanner, two different radioactive sources, 192Ir and 137Cs, were placed together into a single lead collimated system. The CT is capable to determine and differentiate the attenuation coefficients of materials constituted of three phases (gas, liquid and solid), using two or more different radioisotope energies.
