A method for assigning of k-space lines are to echo trains and method for detecting the mr data of, as well as correspondingly configured magnetic resonance systems

摘要

The present invention relates to a method for assigning k-space lines are (z₁–Z₂₄) to echo trains (ez₁–"Ez "₃), in order to use these echo trains (ez₁–"Ez "₃) the k-space lines are (z₁–Z₂₄) by means of a magnetic resonance system (5) to detect. In this case, the k-space lines are (z₁–Z₂₄) in parallel by the k space and the cutting of a plane, which is perpendicular to each schematically (z₁–Z₂₄) is arranged, so that each schematically (z₁–Z₂₄) a respective point of intersection with the plane. Each echo train (ez₁–"Ez "₃) has a length in comparison to. The k-space lines are (z₁–Z₂₄) in such a way be the echo trains (ez₁–"Ez "₃) associated with it, that a sum of all trajectories lengths echo trains (ez₁–"Ez "₃) is minimal. In this case, the length in comparison tl of a echo train (ez₁–"Ez "₃) defined by the following equation: L corresponds to the echo train length of the echo train (ez₁–"Ez "₃), P_i corresponds to a point of intersection of the ith schematically of the echo train (ez₁–"Ez "₃) with the plane andcorresponds to the length of the distance from the ith point of intersection for [i + 1] th point of intersection. The echo train (ez₁–"Ez "₃) scans the k-space lines are associated with it in the sequence schematically (z.₄), 2.k-raum-zeile (z₅), .., l - te schematically (z₂₀) starting from.
