Abstract
An optimized multislice data acquisition method and apparatus for magnetic resonance imaging is disclosed. In this new method, instead of forming a set of multislice image sequences in series for a given phase encoding step, initiation sequences corresponding to different slices are interwoven with acquisition sequences in an optimal way depending on the desired initiation sequence time. A number of acquisition and initiation sequences are inserted with different slice combinations, between the initiation sequence and acquisition sequence, i.e., long initiation sequence time is effectively utilized for the other slice data acquisition. With this optimized method, imaging time can be reduced by as much as a factor of four compared to existing methods.
