Method for generating a sequence of spin echo signals, the application of this method in nuclear spin tomography, and a devicefor carrying out and/or for applying this method

摘要

A method and drive for generating spin echo signals by a sequence of equidistant rf pulses of different amplitude and small flip angle , which pulses follow each other in very rapid succession. By proper selection of the amplitude, it is ensured that the sequence of equidistant echo signals so obtained has of an image without numerous gradient switching steps heretofore required.
