T2 and the Spin-Echo Pulse CycleIn preceding chapters, we glibly referred to the T2 decay of the Mx vector after application of the RF pulse. Actually, we oversimplified the case in order not to obscure the understanding of the relationship of Tl and T2 to TR and TE. But now, it is time to delve more deeply into what T2 actually is.

The Fourier TransformWe will eventually show that a Fourier transform is a spectrum. Hence it is necessary to know what a spectrum is.

Gradientsng how these different intensities are arranged in space to produce an image. There are a number of ways of doing this, but in this section, we will be concerned only with the most widely used method: two dimensional Fourier transform (“2DFT”) reconstruction.

The Slice Select Gradientdient imposes a gradual change in the main magnetic field from the head to the foot end of the patient. If we graph the z gradient with the magnitude of the magnetic field on the y axis and the position along the long axis of the body on the x axis, then we obtain the straight line shown in the graph in Fig. 8.1.
