1. A process of machine generating machine executable state-change instructions for a sequence controller of a multi-slice magnetic resonance imaging (MRI) system, said process comprising the steps of: defining predetermined program-change tables T1, T2,. .. Tn of MRI parameter values in a machine accessible memory; defining predetermined slice-specific program segments P1, P2,. .. Pm of machine executable MRI sequencer instructions in a machine accessible memory, which segments are referenced by predetermined respective symbolic addresses and which segments include pointer-references to said tables; and machine replicating a predetermined set of said slice-specific program segments in a predetermined order while indexing the corresponding symbolic addresses and referenced table entries in a predetermined sequence so as to maintain proper correspondence between slice-specific main programs and subroutines in each replicated segment.
