    "description": "Designing and setting up the beam-shaping hardware that makes intensity-modulated treatment possible. A multi-leaf collimator is a bank of narrow metal leaves in the head of the linear accelerator; each leaf moves independently, and the sequence of their positions carves the beam into the shapes the IMRT plan calls for. This covers working out and constructing those leaf patterns for the specific plan, and is done once per plan rather than at each treatment session.",
