Methods: In both machines integrated image guidance systems like cone-beam CT (CBCT) provide patient set-up errors that can be corrected by the respective 6-D couch.  ...  We generated 72 virtual computed-tomography scans (vCT) by deforming planning CTs (pCT) to cone beam CTs (CBCT). Areas that were matched for treatment were used to guide the deformable registration.  ...  Results: At the periphery of the phantom, CT numbers measured in the negative thousands for all materials due to cone beam effects.  ...
