Abstract
Photoacoustic imaging is an emerging novel hybrid imaging technique combining both optical and ultrasound imaging. A short-pulsed laser illuminate the tissue t o generate sound waves called the photoacoustic wave. These sound waves are used to get high contrast, high resolution deep tissue imaging of various parameters. Photoacoustic imaging, like ultrasound imaging, is a multi-scale and multi-depth imaging modality. In this presentation, basics of photoacoustic imaging and several types of photoacoustic imaging systems will be covered. One particular clinical application of photoacoustic imaging is non-invasive sentinel lymph node detection for the breast cancer staging. Several other clinical applications of photoacoustic
