The goals of our laboratory are to investigate and improve ultrasonic imaging methods for clinically-relevant problems. We do this through experimental and simulation methods. We maintain strong collaborations with the Duke University Medical Center where we work to translate our technologies to clinical practice. A focus of our recent work is the development of novel, acoustic radiation force-based methods to generate images of the mechanical properties of tissue, involving interdisciplinary research in ultrasonics and tissue biomechanics.
Parametric ARFI images generated from a gelatin-based tissue-mimicking phantom. The spherical inclusion embedded in the phantom is four times stiffer than the background medium (16:4 kPa Young's moduli), but it is not ultrasonically-visible in the B-mode image. ARFI displacement, time-to-peak, and recovery time images can clearly delineate this inclusion based on its mechanical contrast from the background material.
