The concept of this proton therapy system comes from the image of a butterfly flying on its wings, and the entire treatment chamber is shaped like a huge and warm silkworm chrysalis. The two sides use rising arcs to enclose the operation screen area into the overall shape, forming a huge wing shape, as if it is about to "turn a cocoon into a disc". The main body in color is warm white, and the surrounding is matched with silver metal edges, reflecting the sense of science and technology of the product. The white semi-transparent light of science and technology runs through the entire main body of the product, creating a comfortable and relaxed treatment environment for the cabin.
