Popis:	Time modulated field-gradient-sequences able to selectively phase encode spatial location or flow velocity in NMR signals are described. The specific phase modulation discriminates between stationary and mobile protons.The method is presented in the one dimensional case and has the following advantages: it is sensitive to flow direction and unaffected by the relaxation times.
