Attaching the Overlays and Carrier Plates

Before you Begin
Due to their construction, the carrier plates can only be attached to the target positioner in one
position.
If required, remove the top aluminum panel of the Stereotactic Target Positioner to save weight.
How to Attach the Overlays and Carrier Plates
Steps
The surface of the carrier plates is not scratch proof.
Correct Alignment
Do not perform patient treatment if the imprinted frame and positioning marks on the target
positioner overlays are not correctly aligned with the carrier plates.
Do not perform patient treatment if the carrier plates do not fit correctly to the
corresponding position on the target positioner or if the frames are not correctly aligned.
To prevent the carrier plates/overlays from shifting, do not touch them after they have been
attached.
Hardware User Guide Rev. 4.9 RT / RS Stereotactic Hardware
Print out the target positioner overlays using your Brainlab treatment planning system
1.
(see the corresponding user guide for details).
2. Cut the corners of the overlays diagonally and laterally along the marks provided.
Place overlay A onto carrier plate A, and adjust it until the marks on both components
3.
match.
Use adhesive tape ③ to secure the overlay to the carrier plate ① (Figure 44).
4.
Verify that all marks and frames have been correctly aligned before proceeding.
Attach carrier plate A to side A of the target positioner while ensuring that all marks
5.
and frames are correctly aligned.
Continue attaching carrier plates B, C and D (with overlays B, C, and D, respectively)
to the corresponding sides of the target positioner.
NOTE:Brainlab provides an alternate plate C if the mask protrudes into the normal
6.
plate C (anterior carrier plate) near the nose. This alternate plate C features a cutout to
make room for the mask. If you use the alternate plate C, cut out a section from over-
lay C to accommodate the mask and carrier plate cutout.
7. Verify again that all marks and frames are correctly aligned.
