Since its first demonstration of functional imaging
in small animals about a decade ago, photoacoustic
tomography (PAT) has quickly become one of the fastest
growing biomedical imaging modalities. Combining optical
excitation with acoustic detection, PAT can provide
detailed images of tissues deep in the body. While PAT
technology continues to improve significantly, substantial
efforts have also been made to develop multimodal PAT
systems. These systems not only provide complementary
information for more comprehensive characterization of
tissue, they also generate data that can be used to further
improve PAT reconstruction. This review will present
current progress in multimodal PAT imaging, focusing on
the technical aspects of integration and its applications in
biomedicine.
