摘要
In a magnetic resonance method and apparatus for time-resolved acquisition of magnetic resonance data in an examination region of a magnetic resonance imaging scanner, an object being examined is placed on a table and is continuously moved through the examination region, magnetic resonance signals are acquired from the examination region while the object being examined is continuously moved with the table through the examination region and prior to the acquisition of magnetic resonance signals, a phase coding that corresponds to a position in k-space, for the purpose of sampling k-space, is carried out. An interruption of the movement of the table takes place at a predetermined table position, and the acquisition of magnetic resonance signals from an examination region is continued over the course of a predetermined time period, while the table (13) is at rest in the predetermined position. At least while the table is at rest, the phase coding takes place such that acquisitions are made in alteration of a predetermined number of magnetic resonance signals for filling a first region of k-space with magnetic resonance data and a predetermined number of magnetic resonance signals for filling a second region of k-space with magnetic resonance data.
