Abstract

The present invention relates to a method of generating and processing spectral information arising from the laser induced fluorescence of tissue. The intensity of fluorescence is recorded as a function of both excitation and emission wavelengths and contour maps of tissue fluorescence are generated which are useful in the diagnosis of condition of the tissue under examination.
