Abstract

There can be a large variation in response between laser treatments of vascular malformations like port-wine stains even in one patient. This could be ascribed to variations in the skin properties like tint (melanin) and perfusion (redness) which will influence the effectiveness of the laser dosimetry. To obtain a better understanding of the relation between skin properties just before treatment, laser dosimetry and clinical response, a multi-spectral dermatoscope is applied. A sequence of calibrated images is captured from 400 to 720 nm. Images at the treatment laser wavelength (532 nm) show the absorbing structures during laser exposure. Images of different treatment sessions of one patient were matched with dedicated registration software to quantify the results of the laser treatment (change in blood vessels structure, effect on pigment). For feasibility, images were collected from 5 patients and used to determine the optimal wavelength combination strategies. The image matching software gives an objective impression of the improvement, e.g. the clearing of the port-wine stain over time or pigment reactions, which will facilitate the discussion with the patient about the end point of treatment. The multi-spectral dermatoscope and software developed enables the evaluation of large patient series which will result in objective data to advise the dermatologist on the optimal laser dosimetry in future in relation to the skin properties.
