Abstract

A novel detection method for malignant tumour detection through specific accumulation of far-red emitting photosensitisers, has been developed. The set-up, based on He-Ne (633 nm) excitation was tested with phantom malignancies models using photosensitisers on chicken tissue. Intensity vs. depth of tissue measurements as well as photobleaching measurements were performed. Point by point fluorescence imaging indicated that the formation size is not significantly distorted with respect to depth of location.
