Multi‐colour fluorescence imaging in connection with photodynamic therapy of δ‐amino levulinic acid (ALA) sensitised skin malignancies

Research output: Contribution to journalArticlepeer-review

Abstract

A system for multi‐colour fluorescence imaging of tissue is described. The instrument is mainly developed for tissue diagnostics to identify and localise malignant tumours, but might also be useful for real‐time monitoring of the therapeutic dose delivered during photodynamic therapy. In vivo examples from various malignant skin lesions following topical δ‐amino levulinic acid (ALA) administration are presented. The diagnostic system utilises both characteristics of a fluorescent tumour marker, such as a porphyrin containing substance, and the native tissue autofluorescence to characterise the tissue. A dimensionless function of three or four simultaneously recorded fluorescence intensities is formed and an optimum‐contrast image is calculated pixel‐by‐pixel.
