1D PHASICS pulse sequence. The open rectangle on the RF axis represents the 90° nonselective pulse; Ga the frequency-encoding gradient; Ta the duration of encoding gradient with single polarity; Na the total number of bipolar encoding gradients; GS the compensation gradient to adjust positions of echo centers. |
