| 1. A magnetic resonance imaging system comprising:
a receiver system to acquire magnetic resonance signals;
a reconstruction unit to reconstruct a magnetic resonance image from the acquired magnetic resonance signals; and
a control system to control the receiver system to
perform an acquisition sequence to acquire the magnetic resonance signals in several acquisition segments,
wherein respective groups of acquisition segments involve acquisition of magnetic resonance signals in different RF-receiver
frequency bands,
the control system is arranged to perform oversampling in the signal acquisition in lower RF-receiver frequency bands, and
the reconstruction unit is arranged to account for the oversampling.
