Photoacoustic imaging relies on laser-generated ultrasound to produce high resolution 3D images that can provide information on the spatial distribution of tissue chromophores. Since blood is the strongest absorber in the visible to near-infrared wavelength region, these images typically represent the tissue vasculature. Using multiple excitation wavelengths, photoacoustic imaging also has the potential to provide quantitative imaging capabilities, which is vital for functional and molecular imaging. A major application for photoacoustic imaging are preclinical studies of human diseases and the development of novel therapies in small animal models. In this talk, I will present an overview of the all-optical imaging technology that has been developed in the Photoacoustic Imaging Group at UCL, and show results from recent preclinical applications, such as photoacoustic imaging of the development and treatment of subcutaneous tumors and a feasibility study into imaging mouse embryos. I will also give a brief overview of our work in the field of quantitative imaging.
