MLCi2 multileaf collimator

Elekta’s MLCi2 multileaf collimator helps achieve a fine balance between the delivery of high doses to the target and reduced dose to healthy tissues outside of the target volume. MLCi2, which provides low integral dose even when using advanced delivery techniques, is driven by Elekta’s fully integrated digital control system.

Unlike non-digital systems, there is no lag in the transmission of information, ensuring continuous verification and accurate placement of all leaves. This allows faster, safer and more accurate delivery than non-digital systems.

The active leakage reduction mechanism in the Elekta MLCi2, uses diaphragms in both directions to automatically track the trailing leaf, thus reducing transmission. This feature plays a valuable role in reducing integral dose to the patient and therefore reducing the risk of induced secondary cancer.
