Single Wavelength

Listen to the Light: Visualizing Deep Optical Signals with High Resolution!

PA-Mode Single Wavelength allows the detection and fusion of photoacoustic signals with detailed anatomical images. Using a tuneable near infrared laser, the subject is illuminated at the desired wavelength (680-970nm and 1200-2000nm*) in order to visualize chromophores such as hemoglobin, melanin, dyes and nanoparticles.  These signals are localized to specific anatomy as visualized through simultaneously acquired high-resolution ultrasound images.

PA-Mode Single Wavelength features:

  • Real-time (up to 20 Hz) frame rate for capturing dynamic processes such as perfusion
  • 2D and 3D acquisition
  • Quantification of photoacoustic signal intensity
  • Frame averaging for higher signal-to-noise ratio
  • Gain compensation for more uniform signal with depth
