AI Technical Summary
Traditional techniques cannot predict the treatment effect on pigmented areas before phototherapy, making it difficult to evaluate the nature of the pigmented spots.
By delineating skin areas containing pigmentation, measuring vascular density, and determining the attributes of the pigmentation based on vascular density, blood flow images of the skin area are obtained using image analysis technologies such as OCT and laser speckle flowmeter. The correlation coefficients between vascular density and melanin value and brightness ratio are calculated to predict the effect of laser treatment.
It enables high-precision evaluation of pigmentation attributes before phototherapy, predicts treatment effects, and improves the accuracy and objectivity of pre-treatment pigmentation evaluation.
