Couchmount Adapters: Brainlab Headring Models

Overview
When using an Elekta couch, choose your couchmount adapter by the location of the lesion. The
following couchmount adapters (see Page 31) are available for use with the Elekta couch:
• Couchmount Adapter Brainlab Headring for lesions on the lower head, between +30 mm
and +110 mm in the cranial direction. This adapter extends further in the longitudinal direction
to compensate for the limited movement of the couch.
• Couchmount Adapter Brainlab Headring (for Elekta Couch)for lesions of the upper head,
between -50 mm and +30 mm in the cranial direction. This adapter moves the treatment area
by 11.5 cm in the cranial direction (if the Elekta couch has already been completely moved
towards the foot end).
NOTE: The values are read from the vertical coordinate on the Stereotactic Target Positioner.
