Magnetic Resonance Imaging

SPEAKER: Dr Chan Taw Kuei  
Lecturer
Department of Physics
 National University of Singapore 

This session provides an overview and a practical session on magnetic resonance imaging (MRI). Participants will be introduced to nuclear magnetic resonance (NMR) which includes nuclear spin, magnetic moments, larmor precession and frequency, the collective behaviour of large number of nuclear spins, bulk magnetisation, 90 radiofrequency pulse and spin rotation; relaxation processes which include T1 and T2 relaxation and time constants, image contrast, T1 and T2 weighted imaging; MRI which include slice selection, frequency and phase encoding gradients; hardware such as the MRI scanner setup, gradient coils and MRI safety. There will also be a hands-on session at the Medical Physics teaching laboratory. Participants will be shown parameter optimisation and T1 and T2 weighted imaging. This may be combined with other experiments to be conducted within the same session.
