Claim Text:
1. A method to generate a magnetic resonance (MR) phase contrast angiography image of an examination subject, comprising: operating an MR data acquisition unit, in which an examination subject is located, by executing an MR angiography pulse sequence that includes activation of a phase coding gradient and a readout gradient, and impressing velocity-dependent phase information on moving nuclear spins in the examination subject by activating additional bipolar coding gradients in said sequence; reading out MR signals from the examination subject in said sequence in raw data space using a non-Cartesian acquisition pattern during said readout gradient, and activating said additional bipolar coding gradients along a coordinate system that corresponds to the non-Cartesian acquisition pattern, with a coordinate axis of said coordinate system proceeding along said readout gradient; and in a processor, reconstructing the MR signals in raw data space to generate an MR phase contrast angiography image of the subject, and making said MR phase contrast angiography image of the subject available at an output of the processor in electronic form as a data file.
