Biaxial driving technique for ultrasound generation with ferroelectric materials
(2021)Over the years, ferroelectric materials have been used in a wide variety of applications in the health care field in applications such as thermal therapy, medical imaging and lithotripsy, just to mention some of them. One ... -
Compact magnetic resonance-guided high-intensity focused ultrasound phased array system
(2021)Phased array ultrasound transducers (Txs) can induce electronically controllable localized hyperthermia to tissue deep within the human body. This localized heating can be applied to tumours as an adjunct therapy in ... -
Design and Development of Dual Tuned 19F and 1H RF Birdcage Coils for Small Animal MRI at 3T
(2015)Conventional proton (1H) magnetic resonance imaging (MRI) is generally insensitive to the lung due to the low tissue density and other complicating factors. On the other hand, inhaled inert fluorinated gas MRI is a ... -
Exploring the feasibility of wireless sensor networks within the MRI environment
(2012-11-10)Wireless communications have long since been utilized to connect a multitude of devices quickly and easily to a common network. However, such methods have not yet been implemented inside a Magnetic Resonance Imaging (MRI) ... -
FEM based analysis of highpass birdcage resonators for B1 field mapping
(2016)3D full wave finite element method (FEM) based electromagnetic (EM) analysis is a technique to map EM fields generated by electrical devices. To better understand and apply this technique to magnetic resonance imaging (MRI) ... -
An Integrated Full-bridge Class-DE Ultrasound Transducer Driver for HIFU Applications
(2016)This thesis present a CMOS integrated transducer driver for high intensity focused ultrasound (HIFU) applications. Because this driver will be used in a magnetic resonance imaging (MRI) environment, no magnetic components ... -
Localized harmonic motion imaging
(2012-11-10)Localized Harmonic Motion (LHM) Imaging is a new technique of ultrasound imaging which uses the localized stimulus of the oscillatory ultrasonic radiation force as produced by a modulated signal, and estimates the resulting ... -
Prediction of overheating close to bone interfaces generated by high intensity ultrasound transducers
(2014-01-22)One of the driving forces for research in medical sciences is to develop more effective and less intrusive treatments. High Intensity Ultrasound (HIU) is a technique that uses the acoustic field produced by a transducer ... -
RF coils design for small animal MRI lung imaging at 3T using hyperpolarized 129Xe and inert fluorinated gases
(2014-01-22)This thesis described the investigation, construction and testing of two sets of RF coils for their applications in novel lung MRI imaging techniques. In the first part of the thesis, a quadrature-driven birdcage coil for ...
