The Photoacoustic Effect explained:
1. LIGHT EMITTED:
Nanosecond pulsed laser light is emitted causing illumination of the tissue.
2. LIGHT ABSORBED:
The light is absorbed by chromophores causing thermoelastic expansion.
3. SOUND EMITTED:
Soundwaves are emitted and detected by the ultra high frequency transducer.
4. SIGNALS PROCESSED:
The signals are then processed and registered as high resolution ultrasound and photacoustic images.
