Small Field Circular Cones System for Siemens

REF: 50-300

Aktina’s Small Field Circular Collimators are light-weight, simple to use, and extremely accurate. The Adapter has an extremely low profile (similar to a beam block tray) so that collisions are virtually eliminated. Inter-changeable cones are provided over a large range of field sizes and the system can be implemented on your Siemens LINAC without any modification to the Siemens collimator head. The precision LINAC interface is extremely reproducible without any play.
