  The imaging of magneto-dynamical processes has been, so far, mostly a
two-dimensional business, due to the constraints of the available experimental
techniques. In this manuscript, building on the recent developments of soft
X-ray magnetic laminography, we present an experimental setup where
magneto-dynamical processes can be resolved in all three spatial dimensions and
in time, with the possibility to freely tune the frequency of the dynamical
process. We then employ this setup to investigate the three-dimensional
dynamics of two resonant magneto-dynamical modes in a CoFeB microstructure
occurring at different frequencies, namely the fundamental vortex gyration mode
and a magnetic field-induced domain wall excitation mode. This new technique
provides much needed capabilities for the experimental investigation of the
magnetization dynamics of three-dimensional magnetic systems.
