The project aims to augment the capabilities of Magnetic Resonance Imaging (MRI) systems using continuous
wave (CW) transmission and signal reception, in order to image objects using very low excitation power. Whether
articulated mathematically or not, it is the objective of any given MRI sequence to solve an inverse problem,
involving estimation of some subset of the hidden states and parameters of the system, given the observed data.
Exploiting the transient and steady-state CW magnetisation dynamics to solve inverse problems in Magnetic
Resonance spectroscopy and imaging will potentially lead to technological advances in control of the magnetic
resonance signal, and will open new avenues of research in the mature domain of MRI.
