Method and apparatus for acquiring image data in a nuclear magnetic resonance tomography system |
摘要 |
In a magnetic resonance imaging apparatus and method the following pulse sequence is repeated N times for acquiring image data. A first radio-frequency pulse is emitted for exciting nuclear spins, in an examination subject. A second radio-frequency pulse is emitted after a time span for rephasing the nuclear spins. Readout of the resulting nuclear magnetic resonance signal under a frequency-coding gradient takes place after a further time span following the second radio-frequency pulse. After waiting another time span, the first radio-frequency pulse of the next sequence is emitted. The pulse sequence is configured such that the nuclear magnetic resonance signals arising from the second radio-frequency pulse of the n-1th sequence and the first radio-frequency pulse of the following nth pulse sequence do not superimpose.
