Abstract
The present invention relates to an apparatus and a method for influencing and/or detecting magnetic particles in a field of view. To increase the field of view and, at the same time, allow access to the patient during imaging, the apparatus comprises two or more transmit coil sets () wherein neighboring coil sets are partially overlapping, a transmit coil set comprising: a pair () of concentrically arranged selection field coils () for generating a magnetic selection field () having a pattern in space of its magnetic field strength such that a first sub-zone () having a low magnetic field strength and a second sub-zone () having a higher magnetic field strength are formed in the field of view (), and at least one pair () of drive field coils () for changing the position in space of the two sub-zones () in the field of view () by means of a magnetic drive field so that the magnetization of the magnetic particles changes locally, said at least one pair () of drive field coils being arranged parallel to said pair () of selection field coils () and being formed by two neighboring coil loops.
