A PTV of 2 mm was given from the tumor. Patients were positioned by aligning the treatment room lasers to the marked isocentre on the DSPS. For all patients 3D-image registration (automatic bony anatomy) was performed by matching 1st CBCT images with the simulation reference CT (simCT) images to measure the 3D target displacement prior to the treatment delivery every day. The initial setup deviation/ interfraction motion- translational (medio-lateral-X, cranio-caudal-Y, anterior-posterior-Z) displacements in mm and rotational axis (pitch, roll, yaw) in degrees were documented. All transitional errors were corrected online. For residual Interfraction motion a 2nd CBCT was done after correction of initial setup errors and matched with simCT and treatment executed. To evaluate the intrafraction motion CBCT was done at end of every fraction and compared with 2nd CBCT images.
