An MRI apparatus for providing superimposed MRI and plenoptic images is disclosed. The apparatus comprises: magnet poles for creating a homogeneous magnetic field a set of RF coils for generating an RF excitation pulse in the imaging volume of the apparatus, and for acquiring magnetic resonance signals which are due to the RF excitation pulse MR imaging means for converting said magnetic resonance signals into a magnetic resonance image a light-field (plenoptic) camera configured to obtain plenoptic images concurrently with said magnetic resonance images and, superposition means for superimposing said magnetic resonance and plenoptic images. In some preferred embodiments of the invention, the pole pieces of the MRI apparatus are constructed from permanent magnets.
