Conclusion: To conclude, Cyberknife spine cases with beams entering through the arms had better dose falloff and less dose to the organs. This study sheds light on providing the oncologists, radiation therapists, medical physicists, and medical dosimetrists with a more comprehensive picture of dosimetric differences for the patient’s arm sparing in Cyberknife spine cases with an arms-down position.
