Paper Abstract

We investigated the possibility to use the intensity of the time resolved laser induced fluorescence signal (LIF) to discriminate between normal intima and calcified lesions by use of a pulsed dye laser (495 nm, 590 nm) and an alexandrite laser (750 nm). Experiments were performed for 83 specimens consisting of normal intima, fibro-fatty plaques, yellow--white calcified and dark hemmorhagic calcified plaques. At 495 nm an obvious intensity discrimination level was found, 39 of 40 calcified plaques were correctly classified.
