Proposed design of a 1mm catheter-based ultrasound device designed to simultaneously measure plaque composition, artery structure, and hemodynamics in 3D in coronary arteries. The device minimizes disturbances to blood flow from the catheter itself. Assistant Professor Brooks Lindsey is leading a new $2.5 million project to develop the device, which will help doctors assess whether patients need aggressive treatment to prevent a heart attack.

An example of the kind of simultaneous data collection that will be possible with the new catheter-based ultrasound device. This figure shows 3D functional imaging with a prototype forward-viewing device in laboratory models of narrowed vessels: (A) Conventional ultrasound imaging of lesion morphology in straight and stenotic, or narrowed, vessels, with extracted lumen shape shown in yellow, (B) 3D vector velocity imaging in straight and stenotic vessels, and (C) Strain rate imaging of a control vessel model and a model with a soft inclusion on the right inner surface. The proposed system to be built under this project will be smaller and have higher resolution than this prototype. (Image Courtesy: Brooks Lindsey)
