Simultaneous multi-slice magnetic resonance imaging
Abstract/Contents
- Abstract
- The slow acquisition speed of magnetic resonance imaging (MRI) hinders its wider adoption as a diagnostic and research tool. In recent years, simultaneous multi-slice (SMS) MRI has been proposed to accelerate MRI scans. The main focus of this dissertation is to develop a generic and accurate data reconstruction framework, termed hybrid-space SENSE, for SMS MRI. To evaluate the signal-to-noise ratio (SNR) loss in the reconstruction, analytical geometry-factor maps are derived. Under the proposed framework, a matrix-decoding Nyquist ghosting correction method is further developed to conduct slice-specific Nyquist ghosting correction for SMS echo planar imaging. This dissertation also presents work on three other aspects of SMS MRI: one is designing undersampling strategies that generate incoherent interslice aliasing; another is de-signing autocalibrating undersampling schemes; the third aspect is designing signal excitation radiofrequency (RF) pulse with reduced peak amplitude.
