Accessible non-coplanar beam geometry for a left lung target based on the actual machine model and a 3D laser scanned human surface shown in (a). b The non-coplanar surface that can be accessed by the source when up to 120 cm source-to-isocenter distances are used by enabling additional couch shifts. c The non-coplanar surface that can be accessed by the X-ray source for treatment limited to 100 cm isocentric set up. The surface only accounts for a point source and that the effective coverage will be larger due to the typical 40 cm field-of-view
