Summary on Grant Application Form
Magnetic Resonance Imaging (MRI) has revolutionised diagnostic medical imaging. There is now interest in improved electromagnetic design techniques for MRI systems to facilitate novel scanner geometries and minimise undesirable physiological effects (nerve stimulation and vertigo) arising from the use of increasingly high field strengths. This proposal draws together mechanical engineers and physicists to apply numerical techniques from computational mechanics to a hierarchy of forward and inverse magnetic and electromagnetic problems associated with MRI.The objective of this proposal is to develop a novel approach, using forward and inverse boundary element techniques, and apply it to the characterisation and optimisation of the electromagnetic fields generated inside the human body during MRI, in order to:- Generate novel gradient coils, allowing more open access to subjects and/or improving the diagnostic quality of images by allowing larger and more rapidly switched field gradients to be produced- Better characterise the interaction of magnetic fields varying at low frequencies with the human body and use this information to reduce the likelihood of nerve stimulation and other undesirable physiological effects.- Develop optimal radio frequency coils that operate at high frequencies where retardation and skin depth effects pose problems for the generation of spatially uniform magnetic fields.
