5 ppm frequency difference, a fat proton precesses at a slower frequency than a water proton. In a rotating frame at the water resonance frequency, the fat proton cycles in and out of phase with the water proton. Following the excitation pulse, the two protons are in phase (a). After a short time, they will be 180° out of phase (b), then in phase (c), then 180° out of phase (d), then in phase (e). The contribution of fat to the total signal fluctuates and depends on when the signal is detected.
These gradients produce high frequencies (by the Larmor equation) and provide mainly edge definition to the resultant image (Figure 5-6). An alternate way to describe the raw data matrix is called the k space formalism. In this approach, the complex array of raw data points is treated as a two-dimensional grid of points (kx, ky), where each kx value corresponds to a different complex time point in the readout direction and each ky value corresponds to a different phase-encoding gradient amplitude.
The rate of rf pulse application (time ). 5. The efficiency of the protons in giving up their energy (T1 relaxation time). qxd 5/16/2004 8:38 AM Page 25 Relaxation 25 For many MRI experiments such as standard spin-echo and gradient-echo imaging, a steady state of M is present because multiple rf pulses are applied and the repetition time TR between the pulses is nearly always less than sufficient for complete relaxation. To produce this steady state prior to data collection, additional rf pulses are applied to the tissue immediately prior to the main imaging pulses.
