a-c Scheme and Example of patient setup on the rotatable tabletop. Image (c) shows the rotation from head-first to the feet-first-position. (1) Carbon fixation button. (2) Holding bars to facilitate rotation of the tabletop through staff (the patient weight is mainly on the rotational unit). (3) Markers for isocenters 1, 3 and 5. (4) Indexed arm bar. (5) Fixed marker for the baseline table coordinates of the “0” position (0-coordinate couch marker) of the iBEAM evo couchtable (Elekta AB, Stockholm, Sweden) at the linac, to enable the prediction of the final absolute table coordinates for a collision-free treatment delivery
