"Magnetic Nanoparticles for Imaging Contrast and Elastography in Optical Coherence Tomography"

Optical coherence tomography (OCT) provides phase-resolved imaging of biological tissues and is particularly suited for tracking nanoscale displacements with high temporal resolution.  These features are used to track mechanically modulated magnetic iron oxide nanoparticles embedded in tissues, providing both OCT imaging contrast and elastography measurements of the tissue stress-strain relationship.  Possible multi-modal applications with MR imaging are discussed. 

Dr. Amy Oldenburg received her B.S. in Applied Phyiscs at Caltech in 1995, Ph.D. in Physics at the University of Illinois at Urbana-Champaign in 2001, and performed post-doctoral work at the Beckman Institute at Illinois until 2008.  In July 2008 she joined the faculty at the University of North Carolina at Chapel Hill in the Department of Physics & Astronomy and the Biomedical Research Imaging Center, where she is an assistant professor.
