Multispectral system evaluates treatments in dermatology

An advanced multispectral dermatoscope that produces detailed images to track skin changes over time can be used to study changes in the macroscopic structure of the skin. The dermatoscopes are based on standard red/green/blue (RGB) charged-coupled device (CCD) detectors. The multispectral system is calibrated to obtain reproducible measurements. The best acquisition time per wavelength is sequentially determined using a barium sulfate white reference object. The performance of a normal and a multispectral dermatoscope was compared on a port wine stain to evaluate the effectiveness of the multispectral imaging system. Multispectral data for in vivo image analysis has been acquired despite several difficulties and the solutions are being optimized as a correction for image motion during acquisition. The system is used for evaluating dermatological treatments and disease diagnosis over time.
