Modeling And Simulation Methodologies For Spinal Cord Stimulation., Saliya Kumara Kirigeeganage Dec 2018

Modeling And Simulation Methodologies For Spinal Cord Stimulation., Saliya Kumara Kirigeeganage

Electronic Theses and Dissertations

The use of neural prostheses to improve health of paraplegics has been a prime interest of neuroscientists over the last few decades. Scientists have performed experiments with spinal cord stimulation (SCS) to enable voluntary motor function of paralyzed patients. However, the experimentation on the human spinal cord is not a trivial task. Therefore, modeling and simulation techniques play a significant role in understanding the underlying concepts and mechanics of the spinal cord stimulation. In this work, simulation and modeling techniques related to spinal cord stimulation were investigated. The initial work was intended to visualize the electric field distribution patterns in ...


Comparison Of Gilmore-Akulichev Equation And Rayleigh-Plesset Equation On Therapeutic Ultrasound Bubble Cavitation, Zhong Hu Jan 2013

Comparison Of Gilmore-Akulichev Equation And Rayleigh-Plesset Equation On Therapeutic Ultrasound Bubble Cavitation, Zhong Hu

Graduate Theses and Dissertations

The inertial cavitation of bubble clouds has been considered to be the hidden crucial mechanism for recent new therapeutic ultrasound applications such as Histotripsy and the ultrasound drug delivery. Although many models are already put forward to simulate the cavitation process, due to the inaccessible experimental validation, which model works closest to the real world situation is not well investigated. The objective of this thesis is mainly to compare the simulation performance of the popular Rayleigh-Plesset model and Gilmore-Akulichev model exposed to high intensity focused ultrasound in terms of the bubble equilibrium radius, the ultrasonic pressure, frequency and gas diffusion ...
