Abstract

In this report we demonstrate improved three-dimensional optoacoustic tomography in test samples. High quality tomographic data and images were obtained from phantom of mice being 2.5 cm in diameter. Capillaries filled with cupric sulfate, ferrous sulfate and nickel sulfate solutions, and immersed in a scattering medium were used for these tests. The brightness of reconstructed phantom images was found to match accurately the absorption profiles of test solutions. Hence, optoacoustic imaging can be applied in preclinical research to perform in vivo absorptivity measurements to deduce functional information on blood oxygen levels or concentration of contrast agents.
