Abstract

The accurate quantification of lesions located in deep tissue is an important challenge in diffuse optical tomography (DOT), while photoacoustic tomography (PAT) as a non-invasive optical imaging provides high-resolution imaging of optical contrast in deep tissue that can be served as a complementary modality to improve the accuracy of DOT. Here, we coupled advantages of photoacoustic tomography (PAT) to diffuse optical tomography (DOT) for enhancing reconstructed DOT images. Using a priori information provided by PAT was used to reasonably regularize the DOT inversion procedure.. The results show that hybrid DOT-PAT can provide high-resolution image in deep tissue.
