Percutaneous implantation of fiducial markers for imaging-guided radiation therapy

AJR Am J Roentgenol. 2009 Apr;192(4):1090-6. doi: 10.2214/AJR.08.1399.

Abstract

Objective: The use of imaging-guided radiation therapy (IGRT) to treat thoracic and abdominal tumors is increasing. In this article, we review the process of IGRT and describe techniques to implant fiducial markers in the optimal geometry.

Conclusion: Implantation of fiducial markers can be challenging. A better understanding of the physics of IGRT can help optimize fiducial marker placement for precise tumor targeting.
