ION RADIATION THERAPY SYSTEM HAVING MAGNETIC FAN BEAM FORMER |
| 摘要 |
An improved beam forming system for ions used in radiation treatment employs a magnet system of successive quadrupole magnets to convert an ion pencil beam to a fan beam with reduced neutrons production compared with conventional beam spreading techniques using scattering foils.
