RESUMO

Objective To determine whether the quality insurance verification of Cyberknife Synchrony meet the clinical requirements of 3D tumor motion. Methods CT images were collected with modified Sunchrony phantom, and then a Synchrony E2E treatment plan was developed.A ball-cube with EBT film was loaded on the bed,and then placed in different movement directions to implement phantom verification plan.E2E film analysis software was used for film analysis to obtain the tracking error. Results The treatment accuracy of Synchrony in one-dimensional, two-dimensional and three-dimensional directions were 0.91, 1.03 and 0.90 mm respectively. Conclusion The present quality assurance validation method of Synchrony meets the demand of clinical three-dimensional tumor motion.
