Circular Small Field Cone Inserts

REF: 50-302

Inter-changeable cones are provided over a range of 4 through 40mm field sizes (increments of 1mm). Each cone is uniquely recognized by the Elekta LINAC by a simple coding system: code value = size of the cone in mm. This reduces potential errors that could occur at treatment.

The precision LINAC interface is extremely reproducible within virtually no cone movement.
