WebNote that ak = 0 whenever (27rk)/3 = irm for m a nonzero integer. (e) Substituting (21rk)/To for o, we obtain T_1X( =2)T 1 2 sin(7rkT1 /T0) sin rk(T1/T 0) ... Thus all the Fourier series coefficients are equal to 1/T. (b) For periodic signals, the Fourier transform can be calculated from ak as X(w) = 21 ak w-T k=-00 . Signals and Systems WebHalf-Fourier-Acquired Single-shot Turbo spin Echo (HASTE) is a Turbo spin-echo technique that is used for sequential acquisition of high-resolution T2-weighted images. HASTE uses a single-shot technique to acquire sufficient data for an entire image from a single TR. HASTE imaging uses a technique called half-Fourier in phase.

WebApr 3, 2024 · At high-contrast boundaries (jump discontinuity in mathematical terms), the Fourier transform corresponds to an infinite number of frequencies. Since MR sampling is finite, the discrepancy is manifest in the reconstructed image in the form of a series of lines. These can appear in both phase-encode and frequency-encode directions.
