MASEP developed the rotary gamma system in China. The rotary gamma system uses 25 Cobalt sources distributed in a spiral mode, and rotates with collimator to precisely target a selected lesion. It's features the precision focusing of the Leskell gamma knife, yet allows for dynamic gamma beams, instead of the static beams provided by the non-rotational Leskell design. The advantage is obvious.
It delivers the same dose rate at the focal point while reducing the number of radioactive sources. This technique provides less harm to healthy tissues. The focal point is sharp and crystal clear.
