The gantry of the linear accelerator moves to position, the computer driven MLC then conforms to the shape of the desired treatment radiation beam, and a dose of radiation is delivered to the desired target. Varying intensities of the total dose delivered results, as seen in the graphic at the bottom of the screen

The Varian linear accelerator is the only accelerator made that is capable of delivering a continuous beam of cancer killing radiation while the gantry and the MLC are in motion. This may allow for a more desirable, uniform dose of radiation being delivered to the desired target, as seen in this clip, in the graphic at the bottom of the screen.

The computer control of the Varian Millennium 120-Leaf, MultiLeaf Collimator (MLC) is so precise, that a computer program can be written to control the radiation exposure so accurately that it can produce artistic detail on an exposed x-ray film. This, of course, is a demonstration of the control capable when shaping the radiation beam to conform to treatment of an irregularly shaped tumor.
