Multi-leaf collimator

A system for controlling a multi-leaf collimator, comprising:

• at least one storage device including a set of instructions for controlling a movement of the multi-leaf collimator;
• at least one processor in communication with the at least one storage device, wherein when executing the set of instructions, the at least one processor is configured to cause the system to:
• determine a target position that a leaf of the multi-leaf collimator needs to reach;
• and
• actuate, by a first drive component and a second drive component, the leaf to move to the target position, wherein the first drive component and the second drive component are both connected to the leaf, and each drive component independently actuates the leaf.
