Ultrasonic Characterization of Atherosclerotic Plaque using Multiple Scattering

Sponsor: National Institutes of Health (NIH)

Start Date: 9/30/16

End Date: 7/31/17

Abstract

Atherosclerosis is the leading cause of morbidity and mortality in Western countries, in large part due to plaque rupture. Vulnerable plaques are the most likely to rupture, being the major cause of acute myocardial infarction and sudden cardiac death. Neovascularization of the arterial walls by adventitial vasa vasorum appears to participate in the progression of atherosclerosis and atherosclerotic plaque neovascularization was shown to be one of the strongest predictors of future cardiovascular events. No techniques are currently available for the quantitative assessment of vulnerable plaque, which remains an unmet need. Microbubbles are extremely powerful contrast agents for ultrasonic imaging of the vasculature and Contrast Enhanced IntraVascular UltraSound (CE-IVUS) seems to be one of the most promising imaging modalities for the detection of atherosclerosis and vulnerable plaque. However, although this technique allows the detection of the vasa vasorum, CE-IVUS currently does not provide a quantitative characterization of its micro-architecture. The specificity of CE-IVUS has to be improved. A quantitative assessment of the vasa vasorum network in vivo would strongly predict cardiovascular events yet no such techniques currently exist. We propose using ultrasound multiple scattering to characterize the microstructural properties of neovascular networks. By using ultrasound multiple scattering to characterize the architecture of the neovascularization, we will add a new dimension to CE-IVUS. With the technique we propose to develop here, CE-IVUS will not only be used for the detection of plaque related neo-angiogenesis, but also for its characterization. This will dramatically increase the specificity of CE-IVUS for the assessment of plaque vulnerability. It will enable the ultrasonic assessment of the vasa vasorum to become a widely used clinical tool for screening, diagnosis and monitoring of plaque vulnerability.

Laser Ultrasound Patch Using Carbon Nanofiber Composites

Sponsor: NCSU Research and Innovation Seed Funding Program

Start Date: 7/01/15

End Date: 6/30/16

Abstract

Unlike the conventional ultrasound transducers with cables, the proposed laser ultrasound is wireless and capable of unprecedentedly remote delivery of ultrasound energy for drug delivery, therapy, and health monitoring of biological and industrial structures. The specific goal of the proposed work is to investigate the carbon nanofiber composites and the associated laser-ultrasound patch (LUP) for ultrasound generation and detections. Specific tasks include: 1) laser ultrasound transduction mechanism study and the LUP transducer design; 2) Fabrication of carbon nanofibers (CNF) with desired optical, thermal and elastic properties and CNF/polymer composite fabrication; 3) CNF characterization, CNF/polymer composite characterization and LUP acoustic characterization; 4) Laser ultrasound tests for drug delivery, thrombolysis, and non-destructive evaluation. This is a truly multidisciplinary research, preliminary data collected under this project will strengthen our future proposals on using laser ultrasound for minimal invasive surgery, drug delivery and wearable electronics to NSF, NIH, DOE and DOD.

Surface and Domain Nano-Engineering of Relaxor Single Crystal for Acoustic Sensors

Sponsor: US Dept. of Defense (DOD)

Start Date: 6/01/15

End Date: 5/31/18

Abstract

Relaxor single crystals are the state-of-the-art piezoelectric materials and are promising for many acoustic sensors. Further increasing dielectric constant, piezoelectric coefficients and coercive field has been difficult, yet critical to achieving the next generation naval devices. In this project, surface and domain nano-engineering methods are investigated to increase dielectric and piezoelectric properties of relaxor crystals for small signal naval devices (e.g. ultras-sensitive vector sensors). Domain wall nano-engineering is studied to enhance coercive field of relaxor single crystals for large signal naval devices. Surface and domain nano-engineering theory, micro/nanofabrication methods for surface and domain engineering, and domain characterization methods will be extensively investigated. The expected results will enable more efficient naval acoustic sensing and acoustic transmitting, and energy harvesting from ambient environment. The high electrical energy density will also enable actuators with low driving voltages and power consumption. In addition to the naval sensing and actuating, the relaxor crystals with nano-engineered domains and nano-composite electrodes hold great potential for structural health monitoring (SHM) sensors, bio-sensors, novel advanced actuators, and transducers for biomedical and aerospace applications.

Start Date: 9/22/14

End Date: 9/11/15

Abstract

Collection of high quality tumor biopsies with sufficient material for biomarker profiling is essential for full implementation of precision medicine for cancer patients. In this project, tissue elasticity, and pressure information will be innovatively detected using a single ultrasound transducer mounted at the tip of the device. The transducer will use the advanced single crystal composite material, which has high sensitivity and wide bandwidth, and will be used for Doppler flow detection for the first time, as well as pulse-echo tests and pressure sensing. By analyzing the measured multiple parameters in real time, the proposed device can be used to significantly enhance the biopsy success rate by sampling at high tumor content areas.
