AAPM Members, Affiliates and Non-Member Affiliates - Login for access to additional information

Charge

1. Review different types of applications of target surrogates in radiation therapy, including gold markers, carbon markers, surgical clips, long-lasting contrast agents, and localization coils. Issues related patient complication, marker migration, dropping, deformation, and different radiographic properties of different types of markers with kV and MV imaging will be addressed.Minimum numbers of fiducials and consequences of insufficient numbers of fiducials will be discussed. The timing between the implantation and planning imaging acquisition will also be addressed to minimize the systematic setup error associated with trauma induced distortion. Recommendations will be provided for physics to assess the quality of marker placement. Guidelines will be proposed for specific treatment sites, such as prostate, lung, live, pancreas, and breast.
