Abstract
An apparatus for operation in a magnetic particle imaging mode for influencing and/or detecting magnetic particles in a field of view, and for operation in a magnetic resonance imaging mode, includes a selector having a selection field signal generator and selection field coils, a driver having a drive field signal generator and drive field coils for changing the position in space of the two sub-zones in the field of view by a magnetic drive field so that the magnetization of magnetic particles changes locally, and a focuser having a focus field signal generator and a focus field coil unit for changing the position in space of the field of view by a magnetic focus field. The focus field coil unit includes at least six focus field coils arranged for generating magnetic focus field components in different directions, where a first set of at least three focus field coils is arranged on a first side of the field of view and a second set of at least three focus field coils is arranged on a second side of the field of view opposite said first side.
