Patient-specific three-dimensional concomitant dose from cone beam computed tomography exposure in image-guided radiotherapy.

Abstract

The additional dose from on-line IGRT procedures can be clinically relevant.

The organ dose can be significantly reduced with the use of appropriate patient-specific settings.

The concomitant dose from CBCT should be accounted for and the acquisition settings optimized for optimal IGRT strategies on a patient basis.
