Abstract
In a method and a magnetic resonance system to automatically determine parameters of a phase contrast flow measurement, a phase contrast pre-measurement with a flow coding sequence is implemented in a predetermined volume segment of an examination subject, and the flow coding sequence is varied in terms of its parameters so that a pre-measurement is respectively implemented for multiple different parameter sets of the flow coding sequence. A model is automatically determined with which a dimension of a phase error can be determined for each parameter set in the flow measurement, in that phase values of the pre-measurement which is implemented with the flow coding sequence with the respective parameter set are analyzed. Those parameters of the flow measurement at which the dimension of the phase error is smallest are automatically determined.
