摘要：The present invention relates to an apparatus and a method for influencingand/or detecting magnetic particles in a field of view (28), in particular for examination ofhuman patients. The apparatus comprises i) selection-and-focus means (120) forgenerating a magnetic selection-and-focus field (50), wherein said at least one set ofselection-and-focus field coils comprises—at least one inner selection-and-focus field coil(113, 115) being formed as a closed loop about an inner coil axis (115a), first innerselection-and-focus field coil (115)—a group of at least two outer selection-and-focusfield coils (116-119) arranged at a larger distance from said inner coil axis (115a) than saidat least one inner selection-and-focus field coil (113, 115) and at different angularpositions, each being formed as a closed loop about an associated outer coil axis (116a-119a), and ii) drive means (120) comprising a drive field signal generator unit (122) anddrive field coils (124; 125, 126, 127) for changing the position in space and/or size of thetwo sub-zones (52, 54) in the field of view (28) by means of a magnetic drive field so that
the magnetization of the magnetic material changes locally.
