Real-time Elasticity Imaging

Funded by Columbia University - SEAS Interdisciplinary Research Seed (SIRS) Funding Program (collaborative project with Prof E. Konofagou, Dept. Biomedical Engineering, Columbia University): 01/2017 - 01/2018

The project aims at the development of compressive sampling techniques that can be integrated into medical imaging systems for real-time elasticity imaging of carotid plaques and thereby the timely prevention of ischemic stroke based on their stiffness and thus stability.

PWI images at specific time instants (top), and the spatio-temporal imaging of pulse-wave propagation (bottom).

PWI (Pulse Wave Imaging) images, for different time instants, are presented on the top side of the above figure. The baseline figure is adopted as a reference to ensure the quality of the PWV (Pulse Wave Velocity) estimation, obtained from the spatio-temporal map (bottom), for different levels of compression using wavelets decomposition.
