Abstract

In order to measure the temperature of atherosclerotic plaques, we developed a method to determine the temperature distribution of vessel walls using a three-layer phantom agar model. Under pulsed-laser irradiation, the thickness of upper layer corresponding to fibrous cap overlying the middle layer corresponding to atherosclerotic lesion could be calculated. The temperature was calculated from measured temperature changes under pulsed-laser irradiation.
