Abstract
In a method and apparatus for capturing magnetic resonance data from an imaging volume of a patient in which liquid, such as particular blood, is moving, a bSSFP magnetic resonance sequence is executed in which nuclear spins located within the imaging volume are cyclically excited by radiation of a radio-frequency pulse, using a magnetic resonance scanner. A ramp pulse is used as the radio-frequency pulse, which establishes a flip angle of the spins that is spatially variable within the imaging volume. The flip angle is designed to be lower on a side or the imaging volume from which the liquid flows into the imaging volume than on the side at which the liquid flows out, and the flip angle increases monotonically.
