ABSTRACT:
A method according to the technique of a steady state free precession (SSFP) gradient echo method, in particular, of nuclear magnetic resonance (NMR) tomography, wherein a regular sequence of radio frequency pulses with flip angle α is applied at temporally constant intervals TR, wherein the phase of these pulses is increased in subsequent steps by a constant phase increment, is characterized in that a predetermined phase encoding scheme is performed in such a manner that each individual phase encoding step is identically repeated N times under the following conditions:N is an even number and N≧2;successive measured NMR signals are averaged,which minimizes the artefacts produced due to incrementation of the phase encoding gradients.
