摘要

In cutaneous vascular laser surgery, hemoglobin and melanin are important skin chromophores that influence treatment of port wine stain (PWS) birthmarks. A potential problem in quantitative chromorphore evaluaton is the error in image analysis associated with a number of factors, including nonuniform illumination and skin curvature. In this study, we used a mannequin head model to investigate how the accuracy of image analysis is influenced by view angle and facial curvature. Our results indicate that view angle and facial curvature affect the accuracy of the recorded color information. From this analysis, we propose that optimal view angles can be determined on an individual patient basis to analyze features on different regions of the face.
