Abstract
An MPI method determines calibration and measurement volumes, wherein the calibration volume is larger than the measurement volume and the overall measurement volume is arranged within the calibration volume. Calibration signals are detected and a system matrix S is created. An MPI measuring signal u is recorded, a location-dependent magnetic particle concentration c with magnetic particle concentration values cwithin the calibration volume is reconstructed and the magnetic particle concentration values care associated with voxels in the calibration volume. Magnetic particle concentration values cwhich were associated with voxels outside of the measurement volume are discarded and an MPI image is generated which exclusively contains magnetic particle concentration values cwhich were associated with the voxels within the measurement volume. MPI image data are thereby generated with little artifacts within a short time even in case of high magnetic particle densities outside of the measurement volume.
