| 摘要 |
The present invention relates to an arrangement (10) and a corresponding method for influencing and/or detecting magnetic particles in a region of action (300).To store the required reactive energy a tank circuit (453) is provided, which is preferably operating at the centre frequency of the MPI drive field. Reactive elements (C4, L2 ), in particular capacitors and/or inductors,couple one or more tank circuit (453) to the drive field resonator (454, 220). The coupling strength is preferably varied by switching additional reactive elements (C5 ) into and out of the coupling unit (452) to vary the strength of coupling. |
