Conclusion:

This study presented an investigation on dose perturbations caused by metal mesh/screws and aneurysm clips during proton therapy. Despite relatively small dose perturbation for aneurysm clips (<7%) and no observable dose perturbation for metal mesh, the metal screws displayed a potentially large dose perturbation (<26%) when aligned parallel to the proton beam.
