ABSTRACT:
A method of identifying atherosclerotic plaque versus structurally viable tissue includes the steps of emitting a fluorescent beam at a single excitation wavelength of between 350 and 390 nm at a tissue and detecting and quantifying the emission spectrum of the emitted beam at critical points chosen to optimize the difference between atherosclerotic plaque and structurally viable tissue. The presence of the atherosclerotic plaque is distinguished from structurally viable tissue by the presence or absence of the intensity of emissions at the critical points of optimum distinguishing wavelengths. 8
