Photoacoustic Imaging

Producing Images

Photoacoustic imaging of vein patterns and their oxygen saturation. Scientists are using this to monitor blood flow
Photoacoustic imaging of vein patterns and their oxygen saturation. Scientists are using this to monitor blood flow in the brain and its activity in real-time

Applications

Photoacoustic imaging of a patient’s hand vein patterns
Photoacoustic imaging of a patient’s hand veins at different wavelengths. At different wavelengths, different features become visible.

Disadvantages

A basic photoacoustic setup using multiple lasers and lenses.
