What Is Photoacoustic Imaging?
Photoacoustics (or PA) explained
Photoacoustic imaging allows the delivery of light energy that is absorbed by tissues causing a thermoelastic expansion. This expansion then generates ultrasound waves that are detected by the transducer and produce images of optical absorption contrast within tissues. See infographic.
