Abstract
An apparatus includes a first multileaf collimator comprising a plurality of pairs of beam-blocking leaves each comprising an end portion. The end portions of beam-blocking leaves of two adjacent pairs are configured to collectively form an aperture when the two adjacent pairs of beam-blocking leaves are closed. The aperture may be sized and shaped to allow a radiation beam to pass through for radiosurgery.
