Imaging with magic echoes

For spectroscopic imaging with magic echoes the space encoding sequence can be appended by an MREV8 sequence for frequency encoding of the spectrum in the absence... 

Fig. 24. Top Magic-echo sequence, TREV-16TS, for solid-state imaging with (a) ideally pulsed (b) nonideally pulsed and (c) sinusoidal field gradients. On-resonance RF irradiations along x and — x are sandwiched by 90° pulses (magic sandwich). The hatched magic sandwich consists of four magic sandwiches. Bottom Projections of the one-dimensional test sample (admantane powder) obtained with the TREV-16TS sequence (r = 30 ps) and the field gradients shown in Fig. 18. The RF field was set at 100 kHz.

Fig. 5.14. Magic-echo parameter images of a shear band in a specimen cut from a cold-drawn piece of polycarbonate produced from a series of T2cfrweighted spin-density images, (a) Spin-density image, (b) TJeff image. (Reproduced with permission from Weigand et al. [57].)...

Figure 7 (A)T2e-magic-echo image of a piece of polycarbonate (see schematic) in which a crossed shearband has been created. (B) An image of a sample that has been stretched nearly to the breaking point The regions with high intensity correspond to areas of low molecular mobility.
