Port wine stained patients need multiple laser treatments which each are paused for 3 months per treatment. For clinical evaluation and better understanding of the laser settings used during these treatments, a special developed multispectral dermatoscope is used to quantify the micro vascularization within the port wine stains. The multispectral dermatoscope captures high resolution images of skin tissue with a surface of approximately one square centimeter. For more accurate treatment evaluation of the port wine stain, recapturing of the exact same location is desired. For multispectral image-analyses an elastic match can be performed so that per pixel spectral analyses can be performed.
