Abstract:
1. Method for generation of magnetic resonance images based on a TrueFISP sequence with simultaneous acquisition of the MR images of a plurality of parallel slices of a measurement subject with raw data for the respective slices being entered into a respective raw data matrices, comprising the steps of: a) establishing a number of the slices N to be acquired in a measurement subject, wherein N is at least 2; b) establishing a number of phase coding lines MA per raw data matrix per slice, with a requirement that a quotient of MA and N is a natural number; c) establishing a repetition time TR, a radio-frequency pulse duration RF and a flip angle α for acquiring said slices; d) sub-dividing each raw data matrix into S separate segments to be measured, wherein S is equal to N or a whole-number multiple of N, with a requirement that a quotient Q of MA and S, that corresponds to a number of the phase coding lines per segment, is a natural number; e) acquiring data for all segments S of all slices N, with the time duration, in msec, T and wherein the acquisition of said data for all segments S of all slices N is implemented with a time duration, in msec, for relaxation of the magnetization M z with a relaxation constant T 1 in a slice N that corresponds to a time duration from an end of a measurement of a first segment up to a beginning of a measurement of a second segment of the same slice, thereby obtaining a plurality of raw data matrices filled with raw data respectively for said N slices; and (f) processing each of said raw data matrices by multi-dimensionally Fourier transforming the raw data thereof to obtain image data for each of said slices in a form suitable for visual display, and making said image data available as an output.
