The y gradient is applied in the direction perpendicular to the coronal plane. Now it would seem that we could be able to use frequency in this direction just as we did for the x axis. However, if we did that, then we would not be able to uniquely specify whether a given frequency ...
Examining the structure of the stripes in Figure 14.5 can provide physical insight into RF spoiling and the choice of Φ0.The linear increment of the phase represented by Eq. (14.2) is equivalent to the phase twist imparted by the phase-encoding gradient as it is stepped to Fourier-encode ...
One exemplary method embodiment includes producing an oscillating phase encoding gradient during a readout phase, where the gradient facilitates acquiring data from multiple phase encoding lines during a single readout phase. The exemplary method embodiment may also include reconstructing an image from ...
'Phase encoding' 1 Reply] Category: General Phase encoding Hello, Could someone explain me simply the principle ofphase encoding? I don't understand the principle of applying higher gradient at each step. Thanks ! View the whole threadReply to this thread ...
The gradient pulse amplitude varies while the table moves continuously. This encoding method breaks the relationship of MR signals and reconstructed images away from Fourier Transform. However, it still preserves the correspondence of reconstructed images to MR signals when system parameters such as coil...

(b) Mean frequency (f) and inter-spike interval coefficient of variation (ISI CV) for a chain of 25 oscillators with D = 0.5, and current gradient ΔI = 0.514. Simulation with σw = 0.618 (compare qualitatively to experiments) marked with dashed black lines. c –e, ...
In SPRITE, the phase encoding gra-dients are ramped in discrete steps to reduce imaging times andminimize gradient vibration. Low flip angle RF pulses are employedto cover the sample bandwidth which arises from the high mag-netic field gradients required for short encoding times. This yieldsa ...
