      Optical Coherent Tomography to guide below-the-knee endovascular interventions

      Peripheral arterial disease remains a common cause of leg amputations causing significant morbidity and mortality. Data regarding below-the-knee endovascular interventions is scarce while long-term patency rates via different endovascular revascularization modalities remain limited. OCT offers excellent three dimension endothelial visualization; however its value to guide peripheral interventions has not been studied. We describe the use of OCT to guide endovascular below-the-knee interventions in order to achieve excellent OCT results.

    4. Intravascular optical coherence tomography measurement of size and apposition of metallic stents

      Intravascular optical coherence tomography measurement of size and apposition of metallic stents

      Effect of beam size and catheter position on the apparent size and apposition of metallic stent struts in IVOCT images were examined. Micro-CT data was employed to determine light - stent strut interactions. Simulated results suggest that location of the reflecting regions depend on relative orientation and position of stent struts to the IVOCT beam. Erroneous stent apposition measurements can occur when the IVOCT catheter is at an eccentric position. A method that mitigates stent strut apposition measurement errors is proposed.

    5. Development and application of optical imaging techniques in diagnosing cardiovascular disease (Thesis)

      Development and application of optical imaging techniques in diagnosing cardiovascular disease (Thesis)

      Atherosclerosis and specifically rupture of vulnerable plaques account for 23% of all deaths worldwide, far surpassing both infectious diseases and cancer. Plaque-based macrophages, often associated with lipid deposits, contribute to atherogenesis from initiation through progression, plaque rupture and ultimately, thrombosis. Therefore, the macrophage is an important early cellular marker related to vulnerability of atherosclerotic plaques. The objective of my research is to assess the ability of multiple optical imaging modalities to detect, and further characterize the distribution of macrophages (having taken up plasmonic gold nanoparticles as a contrast agent) and lipid deposits in atherosclerotic plaques. Tissue phantoms and macrophage cell ...

    7. Dual-wavelength multifrequency photothermal wave imaging combined with optical coherence tomography for macrophage and lipid detection in atherosclerotic plaques using gold nanoparticles

      Dual-wavelength multifrequency photothermal wave imaging combined with optical coherence tomography for macrophage and lipid detection in atherosclerotic plaques using gold nanoparticles

      The objective of this study was to assess the ability of combined photothermal wave (PTW) imaging and optical coherence tomography (OCT) to detect, and further characterize the distribution of macrophages (having taken up plasmonic gold nanorose as a contrast agent) and lipid deposits in atherosclerotic plaques. Aortas with atherosclerotic plaques were harvested from nine male New Zealand white rabbits divided into nanorose- and saline-injected groups and were imaged by dual-wavelength (800 and 1210 nm) multifrequency (0.1, 1 and 4 Hz) PTW imaging in combination with OCT. Amplitude PTW images suggest that lateral and depth distribution of nanorose-loaded macrophages (confirmed ...

    1. The Clayton Foundation allows its investigators wider latitude in their research than traditional grant-funding agencies...As a result, rather than focusing on research that will lead to the next funded grant application, investigators can focus on what is most exciting and most likely to impact patient care.
