For a measuring magnetic resonance sequence multi-layer measurement with a variable layer separation and / or variable layer thickness

摘要

A method for determining a control command sequence (as'') for a measuring magnetic resonance sequence with a plurality of individual measurements, the individual measurements, in order to evaluate with respect to a later evaluation parameter and the evaluation results obtained from the individual measurements to a overall evaluation result (ga) to combine the measuring magnetic resonance sequence,the control command sequence (as'') is constructed in such a way that, between different individual measurements at least one sequence control parameter (d₁, d₂, .., d_k, .., d_N) being varied in such a way that the variance of a measurement error with respect to the overall evaluation result (ga) is minimized,the measuring magnetic resonance sequence a multi-layer measurement, and in the individual measurements in each case individual layers (s₁, S₂, .., S_k, .., S_N) of the examination subject (o) are measured and in this case, the layer separation and / or the layer thickness (d₁, d₂, .., d_k, .., d_N) as a function of a cross-sectional area (a₁, A₂, .., A_k, .., A_N) of the examination subject (o) in the relevant layer (s₁, S₂, .., S_k, .., S_N) be varied, wherein the layer separation all the more narrow and / or the layer thickness (d₁, d₂, .., d_k, .., d_N) the smaller is selected, the greater the cross-sectional area (a₁, A₂, .., A_k, .., A_N) of the examination subject (o) between adjacent layers (s₁, S₂, S_k, .., S_N) changes.
