A multileaf collimator is provided. The multileaf collimator may be used for radiotherapy. The multileaf collimator may include a plurality of leaves that are adjustable along a displacement direction for the absorption of rays propagated along a direction of radiation, with opposing leaves relative to the displacement direction with front faces oriented toward each other being displaceable into a closed position. The multileaf collimator may also include a shielding-intensifying planar shape, which in closed position, is characterized by an at least partial overlapping of the front faces relative to the direction of radiation.
