Summary on Grant Application Form
Despite many technological advances, patient motion remains a problem in Magnetic Resonance Imaging (MRI) causing ghosting and blurring in images. Young children are routinely anaesthetised, carrying an associated cost and risk to the patient. In Diffusion MRI, used for characterising stroke and fibre pathways in the brain, motion of the brain due to just the cardiac pulse is enough to seriously degrade high resolution images. This proposal aims to use the latest technology from arrays of receiver coils to detect and correct MR data for patient motion. We will examine the signals from the coils, and with a knowledge of the effects of motion upon the signals, deduce the actual motion and correct the patient data. The 'deduction' requires the solution of simple linear equations made non-linear by the motion. The formulation of the problem in this general way will allow us to make optimum use of any knowledge we have about the coils. This general formulation will be extended to include information about temporal changes caused by the cardiac cycle, and information we have about the patient position. Our work will be applied principally to neurological imaging but has applications in other parts of the body, for example in shoulder and cardiac imaging. We hope our techniques will make possible the imaging of moving patients and allow fibre pathways in the brain to be observed with a resolution not currently possible in patients.
