Abstract
A method for determining the position of at least one ferromagnetic particle () in a liquid matrix () with an MRI system (). An MRI measurement sequence (MS, MS) is applied () to a measurement volume () in which the particle is situated. The measurement sequence includes a plurality of individual measurements (E, E), during each of which there is a spatially encoding gradient switching operation, including an excitation pulse () and signal recording (), via the MRI system. The measurement sequence has a multiplicity of measurement blocks (MB, MB), which each include one or more individual measurements and, in a pause of the spatial encoding, an intermediate gradient (ZW) switched by the MRI system. The intermediate gradients are dimensioned such that, averaged over time, the particle is kept substantially in the same position (M, M) over each measurement block.
