Abstract
The following relates generally to improved techniques for magnetic resonance imaging (MRI). In particular, the following relates to improving techniques of data acquisition and image reconstruction in relation to the 'looping star' pulse sequence, which was developed to reduce acoustic noise. For example, techniques disclosed herein address the problem that looping star pulse sequence suffers from the overlapping echo effect. For instance, some implementations build echo-in and echo-out signal matrixes, and then sum the matrices to create a system matrix.
