New ultrasound device may help detect heart attack, stroke risk
Researchers have developed an ultrasound device that could help identify arterial plaque that is at high risk of breaking off and causing heart attack or stroke.
Dr. Paul Dayton, co-author of a paper on the new device and professor in the joint biomedical engineering department at NC State and Chapel Hill, said existing state-of-the-art technologies are capable of determining if plaque is present in the arteries, but can't tell whether it's vulnerable.
He said that makes it difficult to assess a patient's risk and that their goal was to develop something that could effectively identify which plaques are vulnerable.
Dr. Xiaoning Jiang, an NC State associate professor of mechanical and aerospace engineering, an adjunct professor of biomedical engineering and co-author of the paper, said they developed a dual-frequency intravascular ultrasound transducer which transmits and receives acoustic signals.
He said operating on two frequencies allows them to do everything the existing intravascular ultrasound devices can do, but also makes it much easier for us to detect the contrast agents - or microbubbles - used for molecular imaging and vasa vasorum detection.
The paper has been published in the IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control.
