Toeplitz Random Encoding for Reduced Acquisition Using Compressed Sensing

INTRODUCTION Considerable attention has been paid to compressed sensing (CS) in the MRI community recently (1,2). CS theory allows exact recovery of a sparse signal from a highly incomplete set of samples (3,4), and thus has the potential for significant reduction in MRI scan time. While most existing work has focused on Fourier encoding, non-Fourier encoding has shown some promise (5,6). In this abstract, we design a pulse sequence to implement the Toeplitz random encoding method proposed earlier (6). The experimental results show that Toeplitz random encoding can be realized in practice as an alternative method for CS MRI.
