Title: Listening to Light – Photoacoustic Imaging and Its Biomedical Applications

Abstract: Photoacoustic imaging is a novel hybrid imaging technique combining both optical and ultrasound imaging. A short-pulsed laser source illuminates the tissue to generate sound waves called photoacoustic waves. These sound waves are used to obtain high contrast, high resolution deep tissue imaging of various physiological parameters. Photoacoustic imaging like ultrasound imaging is a multi-scale, multi-depth imaging modality. In this talk various photoacoustic imaging systems with different resolution and depth capabilities and their biomedical applications will be discussed. First a low-cost, high-speed, compact pulsed laser diode-based desktop photoacoustic tomography imaging system for small animal brain imaging will be discussed. Translating photoacoustic imaging into clinic is a challenge. A handheld photoacoustic imaging system based on clinical ultrasound platform will also be discussed for noninvasive sentinel lymph node imaging in small animals. This type of imaging system has high potential for clinical applications. In addition to photoacoustic tomography, high resolution photoacoustic microscopy system for angiogenesis imaging will be discussed. We also discuss about machine learning approaches to enhance the photoacoustic imaging. Combining imaging system with contrast agents opens door for targeted molecular imaging. A few contrast agents for photoacoustic with molecular imaging capabilities will also be talked about.
