Abstract

See full text

A method of ordering slices for interleaved MRI is provided that includes selecting a number of interleaved slice locations (NS) each having a plurality of excitations (NE,S), where S is the slice number between 1 and NS and NE,S may differ for different slice numbers, selecting an excitation duration (TS) of each the excitation in each the slice, selecting a repetition time (TR) between successive excitations of the same slice, TR has a duration of Ni×TS, Ni is the number of interleaved slices per TR period, and arranging the order for the slices such that the total scan time (T) is minimized such that TR is the product of Ni and Ts, where Ni can be arbitrarily chosen between 1 and NT/NE,max where NT is the total number of excitations for all the slices and where NE,max is the maximum number of the excitations for one slice.
