National Synchrotron Light Source Seminar

"Imaging soft tissue structures with high energy x-rays: Contrast mechanisms and applications of diffraction enhanced imaging"

Presented by Dean Connor, University of North Carolina at Chapel Hill

Wednesday, March 10, 2010, 10:30 am — Seminar Room, Bldg. 725

Diffraction enhanced imaging (DEI) is an x-ray-based imaging modality that yields image contrast from the absorption, scattering, and refraction of x-rays. Particularly because of its ability to extract refraction contrast, even from low-density materials, it has proven to be a powerful tool for the imaging of soft tissue features. DEI has already shown significant contrast-to-noise ratio gains over conventional radiography for the imaging of soft tissue in mammography and cartilage, and, most recently has shown the ability to image amyloid beta plaques in the excised brains of a transgenic mouse model of Alzheimer’s disease. Dr. Connor will discuss the contrast mechanisms of DEI, summarize the existing research, and point towards future developments in both synchrotron-based and x-ray-tube-based DEI systems.
