Most heart attacks and strokes are caused by the rupture of lipid-core atherosclerotic plaques in the artery wall. Seeing the heart attack before it happens may potentially save millions of lives. Dr. Wang is developing a new technique named thermo-elastic deformation imaging, targeting early detection of the lipid-core plaques.
The reconstructed TDI image enables assessment of optical and thermo-elastic properties of tissues simultaneously. TDI together with conventional OCT will achieve an accurate diagnosis of diseased tissues including lipid-core plaques.
