Multi-leaf collimator

Multi-leaf collimators use the arrangement and movement of the leaves to shape beams used for cancer treatment. Each leaf is moved by its own motor. The precise shape of the beam enables targeted tumor irradiation, while minimizing the radiation exposure of surrounding tissue. Thus, the collimator is an essential component of a radiation therapy device. The design of the MLC varies with the specifications of the device, from the number of leaves to the individual control interface.
