Abstract

This study describes the use of a microcomputer based assessment and control system, devised by the authors, for the treatment of Port Wine Stains. In the theoretical model under development, the haemangioma was represented as a discrete blood layer within the dermis, the haemoglobin within the red blood cells acting as a target for the laser radiation. Suitable optical and thermal parameters could be chosen to define the haemangioma for a range of lasers of interest. Experience with a pulsed dye laser will be discussed. When the user inputs wavelength and pot size, the microcomputer calculates optical and thermal distributions within the tissue, and indicates the appropriate laser energy. The significance of spot size and incident energy density can thus be assessed for a range of treatment modalities. The computer is interfaced to a scanner assembly which automatically irradiates the entire port wine stain with the dosage previously determined. Experience with this unique system based on an inexpensive microcomputer will be discussed.
