Diagnostic Ultrasonic Imaging, Acoustic Radiation Force Impulse Imaging, Molecular Imaging
A major research focus in the Gallippi laboratory is acoustic radiation force-based elastographic ultrasound technologies, which diagnose and monitor diseases by noninvasively interrogating the mechanical properties of tissue. We design custom imaging beam sequences that are implemented on clinical ultrasound imaging systems, and we develop novel signal and image processing methods to exploit the pertinent diagnostic information in our data. I have a particular interest in adaptive regression methods, including Principle Component Analysis and other Blind Source Separation techniques, as well as in multi-dimensional tissue motion estimation methods. We validate our methods in relevant animal models, and we translate them to clinical imaging.
