This work advances functional imaging with multispectral optoacoustic tomography (MSOT) in two aspects: methodological, by developing and improving the methods for accurate quantification of blood oxygen saturation (sO2); and translational, by using MSOT for functional brain imaging. For sO2 quantification, Eigenspectra MSOT algorithm is improved using the Bayesian framework and deep neural networks. In terms of applications, MSOT is used to visualize the brain activity in deep compartments in the coronal cross-sections; and its spectral capabilities are shown to make it ideal for molecular and structural brain imaging in small animals.
