Abstract
A method and system for shaping a beam from a radiation delivery device includes a moving miniature multi-leaf collimator which can be moved into the field of radiation from the radiation device to shape the beam or moved out of the radiation field of the radiation device so that a second collimator can shape the beam. The movable miniature multi-leaf collimator comprises opposing banks of movable leaves to form a conformal shape when the collimator is within the radiation field. A translation or rotation mechanism can move the left and right leaf banks at the collimator away from and displaced significantly from the radiation beam of the radiation delivery device so that they will not intercept the radiation field. A second collimator device is then used to produce another independent beam shaping within the radiation field of the radiation device. The miniature multi-leaf collimator is adapted to be so displaced into and away from the radiation field without being physically removed from the radiation device.
