Calibration And Validation Of An In Vitro Ultrasound Device To Deliver Targeted Thermal Enhancement Of Hmsc Osteogenesis, Dionne Dawkins
Calibration And Validation Of An In Vitro Ultrasound Device To Deliver Targeted Thermal Enhancement Of Hmsc Osteogenesis, Dionne Dawkins

Osteoarthritis (OA) is a disease that affects millions of people annually, often the elderly, and limits their physical abilities. Current methods of treating OA are often very invasive, and expensive, costing the Medicare system billions of dollars annually. A minimally invasive therapy that can be localized to the affected area that provides both relief and a short recovery time is optimal for treating the disease. For targeted therapy and clinical use, therapeutic ultrasound in the 0.7 MHz to 3 MHz frequency range can provide relief and is convenient, portable and localized. Low-intensity pulsed ultrasound (LIPUS) has been proven in clinical …

Polymer–Based Resonant Waveguide Grating Structure And Its Applications, Antonio Jou Xie
Dissertations and Theses
Resonance waveguide grating structures have been a subject of interest for several decades. This optical technique offers unique advantages when compared with other optical components. This stems from their relatively simple structure comprised of layers, as well as their high reflection efficiency within a narrow spectral bandwidth. Typical resonance waveguide grating structures that exhibit these characteristics are cost effective and fabricated with fewer materials than conventional multilayer resonance structures. Essentially, only a grating, waveguide, and substrate layer are required for its operation. In addition, unique spectral characteristics can be obtained by varying the grating and layer structure. Among these characteristics …
