Objectives
Intravascular vulnerable plaque rupture is one of the most critical factors for acute cardiovascular diseases. Therefore, accurate identification of plaque vulnerability is the most urgent need for early diagnosis. Emerging photoacoustic spectroscopy imaging technology has the potential to accurately detect lipid composition of plaque vulnerability. However, the existing technology cannot achieve high-speed photoacoustic spectroscopy, thus affecting the experimental and clinical application. This project proposes a new high-speed swept source over large bandwidth, based on that a high-speed photoacoustic spectroscopy system will be implemented to collect quantitative spectral information. Based on the quantitative high-precision spectral analysis algorithm, in addition, the system can capture plaque components and other information to help plaque detection.
