✦ Synopsis

A method of solid-state NMR imaging that permits echo Fourier transformation (FT) has been devised using a magic echo train. The echo FT imaging can be implemented simply by modifying the gradient pulse sequence in the previous magic echo imaging (TREV-16TS) so that the one-dimensional k-space trajectory follows the sampling points which are symmetric about the k origin. The implemented ability of echo FT improves the performance of the magic echo imaging: the sensitivity gained by √ 2, the phase correction is made unnecessary, and the digital resolution is doubled. One-and two-dimensional imaging experiments have been conducted on some solid samples, confirming the improved performance and revealing a TREV-16TS adjustment parameter that is critical for the successful echo FT imaging.
