Radiofrequency Pulses For Improved Simultaneous Multislice Magnetic Resonance Imaging
ACKNOWLEDGEMENTS First, I want to thank Dr. Will Grissom for accepting me as his first student four years ago. Working with him has been a wonderful experience, and I have grown both as a researcher and a person under his guidance. Among his many qualities, I admire Dr. Grissom's dedication to his field, his friendly approach, his commitment to his students and his ability to smile and stay com...
متن کاملDesigning and Fabrication of a New Radiofrequency Planar microcoil for mini-Nuclear Magnetic Resonance
Introduction Radiofrequency planar microcoils are used to increase the resolution of magnetic resonance images of small samples. In this study, we aimed to design and fabricate a spiral planar microcoil constructed on a double-sided printed circuit board (PCB). It has four rings with an internal diameter of 241 microns tuned and matched at 63.8 MHz. Materials and Methods To achieve the maximum ...
متن کاملOff-resonance magnetisation transfer contrast (MTC) MRI using fast field-cycling (FFC).
Magnetisation transfer contrast (MTC) is an important MR contrast generating mechanism to characterise the undetectable bound protons indirectly using the decreased signal intensity of the observable free protons. MTC imaging typically employs a range of off-resonance RF pre-saturation pulse with maintaining the RF magnetic field (B(1)) at a specified value. However, this presents a technical d...
متن کاملReorganizing and shaping of embedded near-coalescence silver nanoparticles with off-resonance femtosecond laser pulses.
We demonstrate that 2D distributions of non-spherical near-coalescence silver nanoparticles (NPs) embedded in an ultrathin dielectric film can be reorganized, shaped and aligned by exposure to ultrashort laser pulses. As-grown samples prepared by pulsed laser deposition show a broad absorption band with a surface plasmon resonance (SPR) at 650 nm, which can be blue-shifted down to 440 nm and tr...
