摘要: Photoacoustic imaging (PAI), including photoacoustic microscopy and tomography, is an emerging modality that shows great potential for clinical research from organelles to Organs. Photoacoustic microscopy is renowned for the high-contrast in vivo vascular imaging in deep tissues in the visible optical region. Recently, photoacoustic microscopy has been successfully extended to the ultraviolet region for cell nuclei imaging and the near-infrared region of lipids imaging. Now we further explored PAI in the mid-infrared region that contains rich molecular vibrational information. Our method addresses the low-contrast and low-resolution issues existed in conventional infrared microscopy. This technique can help boost the development of label-free histology. Second, the strength of photoacoustic tomography has been demonstrated in high-resolution imaging of small animal and human organs with centimeters depth. We recently developed a human-breast photoacoustic tomography system that can image a whole breast at high resolution within a single breath hold, which will help the non-invasive breast cancer screening. Finally, the prospects of photoacoustic imaging will be highlighted.
