What Are the Limitations of Multileaf Collimators?
Despite their advantages, MLCs have some limitations. One of the primary challenges is the complexity of treatment planning and delivery. Precise positioning of the leaves requires sophisticated software and highly trained personnel. Additionally, MLCs may not be suitable for all types of tumors, particularly those that are very small or diffuse. There is also the issue of "leaf leakage," where tiny gaps between the leaves allow some radiation to pass through, potentially affecting healthy tissue.
