Overview

Study investigates how acoustic attenuation impacts photoacoustic waves in multilayered human skin, indicating its significance in signal interpretation.

Key Points

  • This research aims to understand how frequency-dependent acoustic attenuation affects photoacoustic wave propagation in multilayered human skin.
  • Utilized a Fourier-domain semi-analytical approach to analyze wave interactions.
  • Incorporated attenuation and dispersion into an existing lossless model.
  • Reconstructed time-domain responses from frequency-domain pressure fields using inverse Fourier transformation.
  • Attenuation reduces the amplitude of photoacoustic signals and alters wave contributions, with higher frequency components more affected.
  • Systematic changes in interference patterns and waveform structure were observed due to attenuation.
  • Dispersion had a minor impact on waveforms overall, contributing to phase variation.
