Abstract Background The purpose of the study was the clinical implementation of a kV cone beam CT CBCT for setup correction in radiotherapy. Patients and methods For evaluation of the setup correction workflow six tumor patients lung cancer sacral chordoma head-and-neck and paraspinal tumor and two prostate cancer patients were selected. All patients were treated with fractionated stereotactic radiotherapy five of .
