Abstract

In the study, we design a real-time multimodal imaging system to identify and differentiate lipid-rich plaques from stable plaques. We have shown that IVPA is able to perform lipid detection in real time imaging mode. We also see potential lipid and calcified region in ex vivo human artery images. In the future, we plan to validate our study with more ex-vivo animal and human artery images to determine the safety and usefulness before moving on to the in-vivo studies.
