Abstract
An arrangement and a method for influencing and/or detecting magnetic particles in a region of action includes a selector 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 region of action. A driver is provided for changing the position in space of the two sub-zones in the region of action by a magnetic drive field so that the magnetization of the magnetic particles changes locally. A receiver is also provided for acquiring signals, which signals depend on the magnetization in the region of action, which magnetization is influenced by the change in the position in space of the first and second sub-zone. Further, a coil arrangement is provided including a surrounding coil and a magnetic field generator such that the surrounding coil almost completely surrounds the magnetic field generator.
