Patent ID: 8532735

Claim:
A device ( 1 ) for examination and use of an electrical field in a magnetic gradient field, containing magnetic particles in an examination area of an object under examination, comprising a. at least one first arrangement ( 2 ) for determining the spatial distribution of magnetic particles in at least one examination area of the object under examination, comprising a means ( 14 ) for generating a magnetic field with such a spatial magnetic field strength profile that a first sub-zone with low magnetic field strength and a second sub-zone with higher magnetic field strength are produced in at least one examination area, a means for detecting signals which depend on the magnetization in the object under examination, especially in the examination area, influenced by a local change in the particles, together with a means for evaluating the signals to obtain information about the, especially time-variable, spatial distribution of the magnetic particles in the examination area; and b. at least one second arrangement ( 8 ), comprising at least one electrical transmit and/or receive unit ( 6 ), comprising at least one voltage generator ( 22 ), at least one terminal contact ( 18 ) connected to the voltage generator and applicable and/or fastenable to an object under examination, and a ground terminal ( 20 ) applicable and/or fastenable to an object under examination.
