Date:<\/strong>\u00a0Thursday, October 31 Title:<\/u><\/b>\u00a0 Ultrasonic Elasticity Imaging with Acoustic Radiation Force<\/p>\n Abstract:<\/u><\/strong>\u00a0 Elasticity imaging involves introducing a mechanical tissue perturbation, imaging the resulting tissue response, and generating images that reflect the underlying mechanical properties of the tissue.\u00a0 Acoustic radiation force impulse (ARFI) based ultrasonic elasticity imaging methods have become widely available in the clinical market over the past five years.\u00a0\u00a0 To date, these methods have found success clinically in the context of hepatic fibrosis staging and breast lesion characterization, with many additional applications under investigation.\u00a0\u00a0 A major focus our laboratory has been the development and implementation of high resolution ARFI elasticity imaging methods for prostate cancer imaging and treatment guidance, with initial in vivo findings demonstrating that ARFI imaging is specific for clinically significant prostate cancer.\u00a0\u00a0 Commercially available ARFI methods that evaluate shear wave propagation to provide quantitative stiffness estimates generally assume that the tissues are linear, isotropic, elastic, homogeneous, and incompressible in order to reconstruct the underlying material stiffness.\u00a0\u00a0\u00a0 Our recent work in shear wave imaging focuses on understanding the sources of error in these systems, and developing methods that address some of the underlying assumptions, i.e. using 3D volumetric imaging to analyze material anisotropy, using multi-dimensional filters and two and three dimensional shear wave monitoring to improve image quality in structured media, and exploring different approaches to estimate shearwave dispersion.\u00a0\u00a0\u00a0 In this talk, I will review the underlying physics and discuss the promise and limitations of these methods.<\/p>\n Short Bio:<\/u><\/strong>\u00a0 Dr. Nightingale is the Theo Pilkington Professor of Biomedical Engineering at Duke University.\u00a0\u00a0 Her research interests include ultrasonic imaging and elasticity imaging.\u00a0\u00a0 She has pioneered the development and clinical translation of acoustic radiation force based elasticity imaging techniques.\u00a0 She is the author of over 75 peer-reviewed journal articles in the areas of ultrasound and elasticity imaging, and has been awarded 10 patents.\u00a0 She has been a recipient of the Klein Family Distinguished Teaching Award, and both the McDonald and Imhoff Distinguished Research and Teaching Awards at Duke University.\u00a0 She has served on numerous NIH and DOD review panels and was a charter member of the BMIT-B and IGIS NIH study sections.\u00a0 She is an Associate Editor for Ultrasonic Imaging, a senior member of IEEE, and a fellow of the American Institute of Medical and Biological Engineering.<\/p>\n","protected":false},"excerpt":{"rendered":" VISE Fall Seminar to be
