Websequences (Carr and Purcell, 1954; Meiboom and Gill, 1958) with several thousand pulses and a short equidistant pulse spacing (tE) allow for densely recording the decaying signal, ensuring a sufficient acquisition time and minimize relax-ation processes due to diffusion. Each of these pulses causes an NMR echo to be the measured signal (Hahn ...
