A magnetic resonance apparatus has a transmission and reception coil
system and a gradient coil system that is designed to generate a gradient
field that is periodic in one spatial direction. The gradient field
and/or the examination subject can be displaced in the spatial direction
of the periodicity to generate a relative position change between the
periodic gradient field and an examination subject, and the transmission
and reception coil system comprises individually-activatable coil arrays
to allow data to be acquired to fill in gaps or resolve ambiguous data
entries that occur due to the gradient field being periodic.
