Abstract Lung cancer is one of the most common cancers in the world. A cancerous tumour is a group of cancer cells that can grow into and destroy nearby tissue. The lungs are the part of respiratory system. Treating lung cancer has been challenge as the target move due to the continuous respiration movement. The Cyberknife Robotic Radiosurgery System (Accuray Incorporated, Sunnyvale, CA) can treat targets that move with respiration using the Synchrony® Respiratory Tracking System (Accuray Incorporated, Sunnyvale, CA). Alignment each treatment beam with the moving target is maintained in real time by moving the beam dynamically with target. The Synchrony system requires fiducial those are placed in or near the tumour to target the lesion and track it as it moves with respiration. The Xsight Lung Tracking System (XLTS) (Accuray Incorporated, Sunnyvale, CA) is a direct soft tissue tracking method for respiratory motion tracking of lung lesions that eliminate invasive fiducial implantation procedures, so that decreasing the treatment time and eliminating the risk of pneumothorax and other fiducial placement complications. The aim of the study is to evaluate the accuracy of the Xsight Lung Tracking System of Cyberknife using CIRA® XLT Phantom. XLT phantom is an anthropomorphic motion phantom which simulates respiratory motion of a human torso and provided radio chromic film-based test capability at locations inside the phantoms that correspond to typical lung tumour and critical structure locations in a patient. The results are well within the limit and the total target error is 0.92 mm and 1.32 mm for Fixed and Iris Collimator paths respectively.
