SPECTER-TEMPORAL STUDIES OF XE-CL EXCIMER LASER-INDUCED ARTERIAL-WALLFLUORESCENCE

We report on spectro-temporal fluorescence studies of cadaver femoral arterial walls at different stages in the progression of atheroscleros is. After excitation with a Xe-Cl excimer pulse, the time course of th e fluorescence spectrum was recorded over time, and time-resolved mult ispectral analysis was performed. Then, under the assumption of linear ity, we derived a linear spectro-temporal kernel (a weighting function ) which describes the temporal behavior of the fluorescence process in dependently of the prise width of the photoexcitation. The data analys is revealed both static and dynamic fluorescence characteristics which exhibited a good correlation with histological findings.
