Gh. Pettit et al., ATHEROSCLEROTIC TISSUE-ANALYSIS BY TIME-RESOLVED XECL EXCIMER-LASER REFLECTOMETRY, Lasers in surgery and medicine, 13(3), 1993, pp. 279-283
The temporal modification of XeCl laser pulses reflected from human ao
rta tissue immersed in saline has been studied. Dynamic tissue reflect
ivity of both normal and atherosclerotic tissues has been examined for
various incident pulse fluences between 0.7 and 6.5 J/cm2. Changes in
reflected pulse duration are observed for fluences at or above 2.6 J/
cm2 with normal tissue targets and 3.0 J/cm2 With calcified plaque. Su
ch reflected pulse analysis may prove useful in identifying tissue tar
gets for ablation during laser angioplasty.
