Abstract

Methods and systems for performing the methods of magnetic resonance imaging (MRI) are presented. The method of MRI comprises: receiving (200) multiple MRI packages (144,146,148), wherein each MRI package is a grouping of multiple MRI pulse sequence parameters each specifying one or more package specific slices, wherein the multiple MRI pulse sequence parameters are adapted for configuring pulse sequence commands for implementing a physiologically gated MRI protocol; regrouping (202) the multiple MRI packages into interleaved acquisition groups (150,152,154,156) such that the one or more package specific slices for any of the multiple MRI packages is not repeated within each of the interleaved acquisition groups; repeatedly (204) receiving a periodic physiological signal descriptive of a physiological state of a subject; repeatedly (206) acquiring k-space data (158) by controlling the magnetic resonance imaging system with the pulse sequence commands triggered by the periodic physiological signal while sequentially adjusting the pulse sequence commands with the pulse sequence parameters of one of the interleaved acquisition groups; and providing (208) the acquired k-space data.
