Upcoming Colloquia (Spring 2024):

Toward Measuring the Stiffness of Blood Clots Using Magnetomotive Ultrasound

Abstract: 

Heart disease is the leading cause of death in the United States, and over 15% of those deaths are the result of blood clots. Medical ultrasound is a versatile, safe, rapid, and cost-effective imaging technique that is typically used to both diagnose and monitor the treatment of these clots. Yet ultrasound is limited in its ability to measure clot stiffness, which is a clinically relevant parameter that can be crucial for assessing risk and making therapeutic decisions. Luckily, physics holds a possible solution! Toward the goal of an ultrasound-based system capable of quantitatively measuring blood clot stiffness, I conduct research using a contrast-enhanced imaging method called magnetomotive ultrasound. In this technique, magnetic nanoparticles are used as a contrast agent to label regions of interest (such as blood clots) within the imaging area. A time-varying magnetic force then causes the nanoparticles, and thus any possible clots, to oscillate. The amplitude of this oscillation is small enough to be safe for the patient, but large enough to be detected via ultrasound, thus providing a unique signature that indicates the magnetically labeled regions. Importantly, this characteristic motion also carries information that I use to make stiffness measurements. This talk will focus on my current progress and future goals toward developing a magnetomotive ultrasound elastometry system.
