The Behaviour of Induction Coils in the High Frequency Range

Design of the ITER high-frequency magnetic diagnostic coils

This paper is an overview of work carried out on the design of the ITER high-frequency magnetic diagnostic coil (HF sensor). In the first part, the ITER requirements for the HF sensor are presented. In the second part, the ITER reference design of the HF sensor has been assessed and showed some potential weaknesses, which led us to the conclusion that alternative designs could usefully be exami...

High-Throughput RF Coils for High-Field MRI

Improvements in signal to noise ratio (SNR) and ease of use of magnetic resonance imaging (MRI) rf coils are needed to improve image quality and patient throughput in high-field MRI. The goal of this Phase II project is to continue the development of novel rf coil topologies and rf balancing circuits that have demonstrated substantially improved technical performance, reduced cost, and greatly ...

High frequency skin ultrasonography in systemic sclerosis

Background: Systemic sclerosis is an autoimmune connective tissue disorder which is characterised by cutaneous and internal organ fibrosis. Raynaud’s phenomenon is the earliest feature and may precede the onset of the disease by months to years. The heart, lungs, gastrointestinal tract, kidneys and other organs may be involved. Our aim was to evaluate skin thickness and echogenicity in systemic...

High Temperature Superconducting Radio Frequency Coils for Nmr Spectroscopy and Magnetic Resonance Imaging

High-temperature superconductivity has a significant opportunity to improve the performance of nuclear magnetic resonance (NMR) spectroscopy and magnetic resonance imaging (MRI) systems. The low rf losses and compact size of superconducting coils allow them to improve the signal-to-noise ratio in applications where the system noise dominates that of the sample under study. These improvements tr...
