magnetresonanzverfahren using a phasenmodulierten pulse sequence with a constant small testing heads already

摘要

the procedure for carrying out magnetresonanzmessungen in a sample in accordance with this invention, in which a first predetermined number of impulsfolgen each with a second predetermined number of pulses, by a defined time interval (t) beabstandet, to anreg and each with a constant amplitude will be created, which is characterised bythe impulsfolgen through a bent function, bent function modulated, whereby after each pulse data scanned. preferably, a quadratzahl m2 of pulses generated in the output are constant, and the walsh transformation in the sequence of stages is also in the performance of constant.this means that the performance of the excitation in time and frequency is constant. the method according to the invention enables the reduction of battery capacity for mobile nmr applications and the level of sar values due to the small anregungsleistung, needed time signals 5 with proper signal-to-noise ratio to produce.
