Intravascular Sonothrombolysis using a Small Aperture Ultrasound Transducer

Abstract: Cardiovascular disease (CVD) remains the number one cause of death and the search for more effective diagnosis and treatment techniques has been of a great interest. Intravascular ultrasound present a great potential in imaging and therapy for CVD and unprecedented challenges to transducer technology. In this talk, small aperture forward-viewing intravascular transducers with center frequency < 1 MHz were designed, fabricated and tested for effective and safe intravascular sonothrombolysis. Despite the small aperture (diameter <1.5 mm) with respect to the wavelength (2.2 mm), and peak-negative-pressure of 1.35 MPa with a corresponding mechanical index of 1.67 was achieved. Significantly enhanced thrombolysis rate was observed by using microbubbles in in-vitro tests. This small aperture low frequency transducer can also be promising for minimal invasive surgery.

Biography: Dr. Xiaoning Jiang is a Distinguished Professor of Mechanical and Aerospace Engineering and a University Faculty Scholar at North Carolina State University. He is also an Adjunct Professor of Biomedical Engineering at North Carolina State University and University of North Carolina, Chapel Hill. Dr. Jiang received his B.S. degree from Shanghai Jiaotong University, M.S. degree and his Ph.D. degree from Tsinghua University (1997). He received his Postdoctoral training from the Pennsylvania State University (1997-2001). He was the Chief Scientist and Vice President for TRS Technologies, Inc. prior to joining NC State in 2009. Dr. Jiang is the author and co-author of two books, 5 book chapters, 9 issued US Patents, over 100 peer reviewed journal papers and over 100 conference papers on piezoelectric ultrasound transducers, ultrasound for medical imaging and therapy, drug delivery, ultrasound NDT/NDE, smart materials and structures and M/NEMS. Dr. Jiang is a member of the technical program committee for a few international conferences including IEEE Ultrasonics Symposium (TPC-5), SPIE Smart Structures and NDE, ASME IMECE, IEEE NMDC and IEEE NANO. He also serves as the UFFC representative to IEEE Nanotechnology Council (NTC), NanoAcoustics Technical Committee Chair for IEEE NTC, IEEE NTC Distinguished Lecturer (2018), an editorial board member for the journal Sensors, an Associated Editor for IEEE Nanotechnology Magazine and a Senior Associate Editor for the ASME Journal of Engineering and Science in Medical Diagnostics and Therapy.
