摘要：
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 (200) wherein neighboring coil sets are partially overlapping a transmit coil set comprising: a pair (210) of concentrically arranged selection field coils (211 212) for generating a magnetic selection field (50) having a pattern in space of its magnetic field strength such that a first sub-zone (52) having a low magnetic field strength and a second sub-zone (54) having a higher magnetic field strength are formed in the field of view (28) and at least one pair (220 230) of drive field coils (221 222 231 232) Fig.9
