Gantries and dose delivery systems

摘要: Particle therapy is a field in remarkable development, with the goal of increasing number indications which could benefit from such treatments and access to therapy. The therapeutic usage particle beam defines technical requirements all elements chain: we summarize main characteristics accelerators, line, treatment room, integrated imaging systems used Aiming at higher flexibility choice treatments, an centers around world have chosen equip their rooms gantries, rotating line structures that allow complete angle. We review current designs. A gantry though quite expensive structure, future development will increasingly consider reducing cost footprint. Increasing also means delivery techniques solving some issues traditionally affected therapy, for example precision presence motion large penumbras low depths. show strategies these fields, focusing on pencil scanning (PBS), give hints about developments.
