摘要
A hybrid imaging apparatus for imaging an object to be examined located in a sample volume can be operated in an MPI mode and in at least one further imaging mode and comprises a magnet arrangement embodied to generate, in the MPI mode, a magnetic field with a gradient B1 and a field-free region in the sample volume, wherein the magnet arrangement comprises a ring magnet pair with two ring magnets in a Halbach dipole configuration, which are arranged coaxially on a common Z-axis that extends through the sample volume, wherein the ring magnets are arranged so as to be twistable relative to one another about the Z-axis. Consequently, it is possible to generate magnetic fields that meet the requirements of both MRI and MPI such that the hybrid imaging apparatus can be equipped for measurements in various imaging modes, including MPI, MRI and CT.
