What Is Photoacoustic Imaging?
Our unique photoacoustic Imaging technology is an in vivo hybrid imaging modality.
This technology combines the sensitivity and contrast of optical imaging with the depth and high resolution of our ultrasound technology.
When pulsed laser light illuminates tissue, the optical absorbers there (such as hemoglobin) undergo thermoelastic expansion, generating an acoustic pressure wave which is detected with an ultrasound transducer.
The ultrasound imaging provides a high-resolution frame-of-reference for identifying anatomy, while the photoacoustic imaging enables functional measurements such as oxygen saturation, total hemoglobin and the microdistribution of biomarkers. Learn more about our Photoacoustic system.
