ABSTRACT:
A plurality of non-overlapping bands is established in k-space. Each band includes a set of lines to be read out between a maximum phase-encoding gradient and a minimum phase-encoding gradient. Similarly, an identical plurality of temporally sequential and non-overlapping subsequences of pulses are established in the MR pulse sequence. Each subsequence corresponds to one and only one of the bands and reads out lines of MR data at phase-encoding gradients that are between the maximum and minimum phase-encoding gradients for that corresponding one. Lines of MR data are read out using the MR pulse sequence and the k-space bands are filled with lines of MR data. Advantageously, the first subsequence is used to fill up the center band in k-space.
