Abstract
Systems and methods for adjusting a beam-limiting device, the beam-limiting device including a plurality of movable components for shaping a radiation beam. The methods may include for each of the plurality movable components, determining an initial location of the movable component; determining a target location of the movable component; and determining, based on the initial location and the target location, a moving route of the movable component. The methods may also include causing the plurality of movable components to move along their respective moving routes. During the movement of the plurality of movable components along their respective moving routes, the shape of an irradiation region of the radiation beam passing through the beam-limiting device may remain unchanged or substantially unchanged.
