A method and system for functional layering of skin epidermal structures based on photoacoustic images
By calculating the first derivative of melanin distribution in the skin epidermis using photoacoustic imaging technology and identifying metabolic activity feature points, a non-invasive, high-resolution functional stratification of the skin epidermis is achieved. This solves the problem of inaccuracy in stratification in traditional methods and provides a new tool for skin health assessment.

AI Technical Summary
Existing technologies lack non-invasive, high-resolution methods to accurately analyze the distribution gradient of melanin in the epidermis. Traditional methods are destructive, have low resolution, or rely on signal intensity thresholds, leading to inconsistent layering results.
A skin epidermal structure functional stratification system based on photoacoustic images is adopted, including a photoacoustic imaging unit, an image processing unit, and a report generation unit. By calculating the first derivative of the photoacoustic intensity distribution curve, feature points with abrupt changes in metabolic activity are identified, and metabolically active areas and terminal differentiation areas are divided. Quantitative analysis is performed using a multidimensional set of quantitative parameters.
It achieves non-invasive and quantitative skin epidermal functional stratification, improves the accuracy and reliability of zoning, and can dynamically monitor skin health status, providing a new tool for skin disease diagnosis and skin care product evaluation.
