Determination of a magnetic resonance - pulse sequence using a combination of various trajektorienverlaufs - functions while taking into account a trajectories - error model

摘要

A method and a control sequence determination of a direction (22) for determining a magnetic resonance system - sequence (as), which at least one of a magnet resonance system (1) - pulse train frequency to be transmitted (mp) comprise. For determining the sequence (as), a target - magnetization (m) is recorded, and a k - space - trajectory (k (t)) is determined. It is then - a high frequency pulse train (mp) for the k - space - trajectory (k (t)) in a hf - pulse - optimization method using a target function (f_z) determined, and the target function (f_z) a combination of different trajektorienverlaufs - functions, of which at least one trajektorienverlaufs - function on a trajectories - error model l (tfm₁, Tfm₂, .., Tfm_M) is based. In addition, a method for the operation of a magnetic resonance system (1) as well as a magnet resonance system (1) with such a control sequence determination of a direction (22) is described.
