Clinical application of cone beam CT in intensity‐modulated radiotherapy for the moderate to severe thyroid‐associated ophthalmopathy

CBCT image guidance for IMRT in moderate to severe TAO improves target conformity and coverage while reducing OAR doses, particularly for lenses. CBCT also shows promise for short-term efficacy assessment of eye prominence in radiotherapy patients which may alleviate patient anxiety with preliminary observation thereby improving patient compliance with radiotherapy.
