The present invention relates to a method for assigning k - space - lines (z1–Z24) to echo trains ("ez "1–"Ez "3), in order to use these echo trains ("ez "1–"Ez "3) the k - space - lines (z1–Z24) by means of a magnetic resonance system (5) to detect. In this case, the k - space - lines (z1–Z24) in parallel by the k - space and cutting edges a plane, which is perpendicular to each k - space - line (z1–Z24) is arranged, so that each k - space - line (z1–Z24) a respective point of intersection with the plane. Each echo train ("ez "1–"Ez "3) has a trajectories length. The k - space - lines (z1–Z24) in such a way be the echo trains ("ez "1–"Ez "3) that a sum of trajectories lengths of all the echo trains ("ez "1–"Ez "3) is minimal. In this case, the trajectories length tl of a echo train ("ez "1–"Ez "3) defined by the following equation: L corresponds to the echo train length of the echo train ("ez "1–"Ez "3), Pi corresponds to a point of intersection of the i -, which is of a k - space - line of the echo train ("ez "1–"Ez "3) with the plane andcorresponds to the length of the distance from the i -, which is of a point of intersection for [i + 1] -, which is of a point of intersection. The echo train ("ez "1–"Ez "3) scans its associated k - space - lines in the sequence 1. k - space - line (z4), 2. K - space - line (z5), .., L - te k - space - line (z20) starting from.
