Evaluation of the clinical usefulness for using verification images during frameless radiosurgery

Thierry Gevaert et al. Radiother Oncol. 2013 Jul.

Abstract

Our previous studies showed that intrafraction motion needs to be corrected for in frameless radiosurgery. This study was designed to evaluate if verification images can correct for mechanical inaccuracy and intrafraction motion. With proper immobilization and verification images on a regular basis during treatment, mechanical (table-) inaccuracies and intrafraction motion can be corrected for and the absence of PTV-margins warranted.

Keywords: 6DOF positioning; Frameless radiosurgery; Verification images.
