Photoacoustic Imaging and Spectroscopy

The Photoacoustic technique is based on detection of ultrasound waves generated in tissue by the absorption of optical pulses (time-domain) or modulated light (frequency-domain) followed by the thermo-elastic expansion of the absorbing volumes. The Photoacoustic uses absorption as contrast mechanism thus we can use as imaging (microcirculation) and spectroscopy (SO2 mapping).
