Overview

Frequency-domain modeling reveals accurate photoacoustic wave generation in multilayered skin, indicating improved imaging techniques.

Key Points

  • To develop a semi-analytical framework for modeling photoacoustic responses in multilayered human skin using frequency-domain analysis.
  • Developed a frequency-domain semi-analytical framework for photoacoustic wave modeling.
  • Incorporated photon diffusion with heat conduction and thermoelastic wave generation.
  • Ensured photon-flux continuity at refractive-index discontinuities.
  • Validated the model against benchmark reference results in multilayered media.
  • Applied the framework to a realistic nine-layer skin model for analysis.
  • Achieved excellent agreement in pressure amplitude and phase with benchmark results.
  • Enabled depth-resolved analysis of photon fluence and thermal behavior.
  • Provided insights into acoustic pressure under physiologically relevant conditions.
