Abstract

A novel skin phantom is described that is constructed with quantifiable amounts of skin pigments, as well as a light scattering medium in the form of barium sulphate suspension. The two predominant skin pigments (melanin and haemoglobin) are varied in controlled amounts within the phantoms to simulate skin colour in different situations. The phantoms were devised in order to simulate the changes in skin colour particularly after laser treatment of port wine stains, where superficial cutaneous vascularity is reduced. Preliminary investigations of two techniques for skin colour assessment were subsequently carried out so that their suitability for measuring colour in the skin phantoms could be considered. A specifically designed device was constructed to enable repeatable digital image capture of the phantoms. Further development of this skin phantom may enable comparison of techniques for skin colour assessment.
