IBA introduced its new Proteus One proton treatment system during ASTRO 2010. It is about one-third the size of current proton treatment systems, taking up about the same amount of space as two linac rooms side-by-side.
The Proteus One is designed to offer more patient access to proton therapy by making the treatment system easier to install. It is also designed to be used as a single treatment room installation, rather than sharing a larger cyclotron and beam with several treatment rooms.
