Pushing The Boundaries In Gradient And Shim Design For Mri, Parisa Hudson
Pushing The Boundaries In Gradient And Shim Design For Mri, Parisa Hudson
Electronic Thesis and Dissertation Repository
High performance gradient and shim coils are highly interested for high-field magnetic resonance imaging and spectroscopy to correct for large B0 inhomogeneities created by the magnetic susceptibility differences between tissues, bone, and air. In chapter two, complete sets of high-performance gradient and shim coils are designed using two different methods: the minimum inductance and the minimum power target field methods. A quantitative comparison of shim performance in terms of merit of inductance, ML, and merit of resistance, MR, is made for shim coils designed using the minimum inductance and the minimum power design algorithms. The coils designed …
