Direct Fourier Transform NMR Tomography with Modified Kumar-Welti-Ernst(MKWE) Method

Direct Fourier transform NMR tomographic method originally proposed by Kumar-Welti-Ernst(KWE) has been modified by double spin echo technique to improve the image quality. This new Modified-KWE(MKWE) method provides two quadrant data set in 2-D Fourier space which is essential for the accurate image representation of the NMR spin density. Further improvement of the MKWE method using the slice encoding technique and spin echo measurement time is also investigated.
