Multileaf collimator
First Claim
1. A multileaf collimator for radiotherapy comprising:
- a plurality of leaves, which are adjustable along a displacement direction and operable to absorb rays propagated along a direction of radiation, opposing leaves relative to the displacement direction with front faces oriented toward each other being displaceable into a closed position, wherein, in the closed position, the front faces overlap at least some of the plurality of leaves relative to the direction of radiation at least in a sub-area.

Abstract
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.

13. A radiotherapy device for shaping X-radiation, comprising:
-
at least two radiation absorbent leaves being adjustable in a direction substantially perpendicular to a direction of radiation, a first of the at least two leaves having a first front face and a second of the at least two leaves having a second front face, wherein the first and second front faces overlap each other in a closed position.
