Overview

Simulation study optimizes laser acupuncture parameters for safe treatments in acupoints, suggesting effective guidelines.

Key Points

  • The study aims to optimize laser acupuncture parameters for effective and safe treatment using a skin model.
  • Constructed a computational skin acupoint model using COMSOL Multiphysics.
  • Employed a multiphysics approach to analyze light source parameters and cooling effects.
  • Optimized parameters included wavelength, beam waist, power, and glycerol layer thickness.
  • Monitored dermal temperature and thermal damage at various conditions.
  • Achieved stable dermal temperature (40.86–42.04 °C) with negligible epidermal thermal damage (0.0063).
  • Controlled conditions maintained dermal temperature for pulsed sources between 38.85 and 40.35 °C.
  • Thermal damage factors remained below the threshold for injury, ensuring safety.
  • Model robustness was demonstrated under ±5% power and ±40% glycerol thickness variations.
