Title:
Guiding cardiovascular intervention with integrated ultrasound imaging
Abstract:
Approximately 19 million people in the U.S. suffer from coronary artery disease. Minimally-invasive procedures in coronary arteries are currently guided by imaging techniques that expose patients and physicians to ionizing radiation while providing only 2D images of complex 3D anatomy. Three novel systems developed in our lab for imaging in different stages of the diagnostic process will be presented. First, a combined CT-ultrasound system for non-invasive, low radiation imaging of coronary artery structure using a CT-compatible ultrasound transducer with an integrated acoustic metamaterial will be presented. Next, development of a forward-viewing, catheter-based ultrasound system for characterizing the coronary mechanical environment within the cardiac catheterization lab will be demonstrated, including in vivo results in a pig model. Finally, a sub-millimeter robotic guidewire-based imaging system will be demonstrated for the >20% of cases with chronic occlusions, in which even the guidewire cannot be routed to the symptomatic lesion.
