Abstract:
In a magnetic resonance system and method the imaging area is readout by: (a) switching at least two phase coding gradients in respective spatial directions, (b) at the full strength of the phase coding gradients, radiating a non-slice-selective RF excitation pulse, (c) after a time t1 after the last radiated excitation pulse, acquiring echo signals entered as raw data points along the radial k-space trajectory predetermined by the strength of the phase coding gradients, (d) repeating (a) through (c) with different phase coding gradients until k-space corresponding to the imaging area is read out in a first region along radial k-space trajectories, depending on the time t1, and (e) reading out a remainder of k-space that corresponds to the imaging area, that is not covered by the first region of k-space and includes the k-space center, in a different manner than by (a) through (d).
