CBCT for cranial patients localized using the CT box; i.e., first, a laser-based setup is done using the target positioner sheets attached to the box. After that, the box is retires and CBCT is used forma the final setup

ExacTrac is our "Gold Standard" for 6DOF alignment. We then verify iso using OBI kV-kV to ensure the same isocenter position was sent to both ExacTrac and the R&V. Also to ensure the correct isocenter is loaded in ExacTrac when there are multiple isocenters.

Usually do CBCT or kV/kV verification after ExacTrac on a Novalis Tx

We do the winston lutz, align the box, CBCT, then take MV's of every arc to match w/ the DRR's from Brainlab to ensure iso w/ table kicks.

Verification is done with a kV-MV pair due to fears of localization on Exactrac using the wrong CT (which used to be possible).

If we are one our brainlab unit we use exactrac. If it is on our non brainlab we use CBCT and Kv kv between beams with isocal and winston lutz done on day of treatment

ExacTrac with the 6D couch and robotics 2.0 for tranlational and rotational shifts applied from outside the vault at the treatment council.
