Abstract

We present a simple fluorescence imaging system for use in the demarcation and monitoring of skin cancers. The imaging system simultaneously acquires four spectrally specific images at 635, 600, 540 and 400nm. The incorporation of an image intensifier, coupled with high speed image processing gives video update rates. The integrated light source is based on low cost fluorescent bulbs, shaped to fit around the lens and phosphor coated to give a peak emission near 400nm, matched to the absorption maximum of PpIX. We apply this system to monitoring the fluorescence of the PpIX photosensitiser before during and after ALA based PDT.
