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