Abstract
A device for alternating examination of a measurement object () by means of MPI and MRI with two magnetic field-generating elements is presented. The device is characterized by a main magnet coil system with two coaxial partial coil systems () arranged mirror-symmetrically relative to a central plane running perpendicularly to the z-axis through the first volume under investigation (). The volumes under investigation are superimposed. A polarity reversal device () reverses the polarity of the current through a partial coil system and the main magnet coil system generates a homogeneous magnetic field of at least sixth order in the first volume under investigation when the partial coil systems have identical polarity, and a spatially strongly varying magnetic field profile in the second volume under investigation when the polarities are opposite. Repositioning of the measurement object is thereby simplified or can even be eliminated.
