Abstract
There is a growing interest in predicting late xerostomia in head and neck (H&N) cancer patients using image biomarkers (IMBs) calculated on CT images acquired at
sparse intervals over the course of radiotherapy. In delivering radiotherapy with image guidance (IG) the TomoTherapy (Accuray, Sunnyvale, CA, USA) system allows
daily IG mega-voltage CT (MVCT) scans to be acquired with ease. The aim of this study was to 1) investigate whether changes in daily MVCT IMBs calculated on the parotid glands could predict late xerostomia (grade>1) and 2) establish the predictive power of the IMBs at different intervals of the radiotherapy course
