Aims and objectives

To give the postgraduate student developing new techniques and instrumentation in EPR, NMR and MRI a general understanding of the technologies used in modern magnetic resonance spectrometers. The range of hardware covered includes magnets, coils and shims, field stabilization techniques, spectrometer transmitter and receiver systems, and microwave-radio-frequency probes.

Syllabus

• Overview of MRI system; Magnets: types and technology
• Shim systems; Gradient systems; Magnetic field design and optimisation; Limits to performance; electromagnets
• Spectrometer systems; Transmit chain; Modulation (amplitude, phase, frequency); RF and µW Power Amplifiers; microwave components; receive units; Signal Processing; Signals and Noise
• Electronics Refresher and RF basics; Tuning and Matching of MR probes; Simple MR probes
• Specialist RF probes; Magic Angle and Double Rotation; Multi-element receivers; Multi-transmit; EPR probes and cavities
