FDA has cleared a ProTom International Holding 510(k) for its Radiance 330 proton therapy system, a compact, single room system equipped with an advanced pencil beam scanning system and integrated imaging and control system. The device can be installed within an interior accelerator vault space of 20ft x 30ft, and requires up to 40% less radiation shielding, the company says. Its pencil beam scanning delivers improved “dose sculpting and higher beam efficiencies than other methods of proton beam delivery,” it says.
