OARs

organs at risk

BACKGROUND The safe use of radiotherapy (RT) requires compliance with dose/volume constraints (DVCs) for organs at risk (OaRs).

RESULTS VMAT-10B showed better target coverage, while VMAT-5B was superior in organs-at-risk (OARs) sparing.

Background To evaluate the effects of dose to tumors and organs at risk (OARs) on inter-fractional anatomic changes.

PURPOSE Clinical target volumes (CTVs) and organs at risk (OARs) could be autocontoured to save workload.

Adaptive radiotherapy (ART) considers variations in target and organs at risk (OARs) anatomy occurring during the treatment course and integrates these in re-optimized treatment plans.
